IWall Street (Mhlawumbi) ayifuni ukuba uyazi malunga neKhowudi yeDada

Uninzi lwezona nkqubo zintsonkothileyo zehlabathi, iikhowudi nemidlalo zimiliselwe kwimathematika. I-Chess, umzekelo, iquka incopho yobunzima, ihlelwe ngokucokisekileyo kwigridi ye-8x8, ngelixa i-tic-tac-toe (X kunye ne-O) ikhupha le ngcamango ibe lula kwi-matrix ye-3x3.

Nangona kunjalo, eyona mfihlelo ibaluleke kakhulu kwixesha lonke , kunye nekhowudi efunwa kakhulu kwimbali - ikhowudi yezemali exhasa iinkqubo zoqoqosho zanamhlanje - yinto esisiseko, umdlalo wemathematika okhohlisayo xa uhlanjululwe ngokupheleleyo.

Ngokungafani ne -chess , eyakhiwe kwi -8x8 matrix , okanye i-tic-tac-toe , esebenza kwigridi ye-3x3 , le khowudi yezemali enzulu isekelwe kwisakhelo se-matrix ezimbini: ezimbini ze-matrices ze-6x6 zesikwere.

I-Matrix A (iDada) kunye ne -Matrix B (Ichibi leentlanzi) zisebenza ngemvisiswano egqibeleleyo, zenza umjikelo oqhubekayo oquka isingqi esingapheliyo sokukhula kunye nokwehla - izinto ezingundoqo ezibumba iinkqubo zemali zelizwe lanamhlanje.

Esi sikhokelo sotshintsho saziwa ngokuba yi -The-Duck-Code .

Nangona kunjalo, ngaphambi kokuba siveze ubunzulu obupheleleyo beKhowudi yeDada , kufuneka siqale sihlolisise ibali lemathematika elisebenza njengesiseko sokudala kunye nokuvela kweemarike zemali zehlabathi.

Kuphela ngokuqonda le ngxelo sinokuthi siqalise ukutyhila kunye nokucacisa iimfihlo zeDuck Code .

Ngeminazana ithile

Iziqalo

Kwichibi elizolileyo, elikude, elibekwe kwikona ephezulu ekhohlo ye -6 × 6 yesikwere se-matrix enezikwere ezingama-36 , idada losana lithatha umoya walo wokuqala kwindawo (0,0) . Ithozamile kodwa itsala amehlo, ivela njengonxantathu we-isosceles onekona ekunene . (umfanekiso 1)

Iimpawu zedada

Indawo ephezulu kanxantathu yintloko yedada, ehlala ifikelela phezulu. Ngaphakathi kumzimba walo omthubi, idada lithwele isisu esiluhlaza, esingqukuva , isangqa esigqibeleleyo esibekwe ngaphakathi. Ukususela ekuqaleni, iphinde ithwale i- backpack engwevu , emise njengomnye unxantathu obonisa umzimba wayo, ekhula ngokulinganayo emva kwayo.

Njengoko idada likhula, ubhaka uyakhula , ukhula ecaleni kwawo kwaye ngokuthe ngcembe wolule de, ngenye imini, igcwalise isiqingatha esingaphezulu sematrix a . (umfanekiso 2)

Ukufuna okugqibeleleyo

Ukususela kwixesha lokudalwa kwalo, injongo yedada kuphela e-e yacaca: ukubaleka imatrix. Kodwa ukuze kuphunyezwe oku, kwakufuneka kuqala kugqitywe imisebenzi emibini ebalulekileyo:

1. Ukufikelela kubude bayo obukhulu ngaphakathi kweMatrix a , kunye

2. Gcwalisa ngaphezu kwe-50% yobhaka wayo ngamanzi (umfanekiso 3)

   
   

Umsebenzi wokuqala

Kumanqanaba amathandathu okuqala obomi balo , injongo yedada ithe ngqo: ukukhula ukuya kutsho kubukhulu balo ngaphakathi kweMatrix a .

Ukuze lenze oku, idada liqalisa ukusela amanzi echibini, likhulisa isisu salo esingqukuva lize liqalise ukukhula .

Ukukhula kwayo kuzinzile kwaye ihambelana , iqhubela phambili kunye ne-diagonal ye-matrix kwi- angle ye-45 ° .

Kwisithuba samanqanaba amathandathu alinganayo, idada liba lide kwaye libe likhulu ngenyathelo ngalinye (umfanekiso 4-5) . Ekupheleni kwezi zigaba zintandathu, umzimba wayo (omelwe ngunxantathu omthubi) ugubungela isiqingatha esisezantsi sematrix. (umfanekiso 5)

Umsebenzi wokuqala ugqityiwe

Xa idada lethu lifikelela kubude balo obuphezulu be-6X , isisu salo sineradiyasi r=1.75X , kwaye intloko yalo ibekwe kwi-coordinate (6,6) . Umphezulu womzimba wedada ngoku ulinganisa i-18X² . (umfanekiso 6)

Umsebenzi wokuqala ugqitywe ngempumelelo lidada.

Ubutumwa bokugqibela - iMatrix b - ichibi leentlanzi

Idada ngoku lilungele umngeni walo olandelayo. Ukusaba kwi-matrix, kufuneka igqibe umsebenzi wayo wokugqibela : igcwalise ngaphezulu kwesiqingatha sobhaka wayo ngogcino lwamanzi kuhambo lwayo olungaphaya kwe-matrix.

Ukugqiba umsebenzi wayo, iMatrix b - Ichibi leentlanzi lingena kwindawo (umfanekiso 7) . Le matrix yesikwere, iyafana neMatrix a, imele ichibi elikufutshane elizaliswe ziintlanzi.

Idama lahlulwe libe ngamacandelo amabini ngokwedayagonali yalo:

1. Isiqingatha esisezantsi , sigcwele iintlanzi , sisuka ukusuka phezulu ukuya phezulu.

2. Isiqingatha esiphezulu sizaliswe ngokupheleleyo ngamanzi .

   
   

   

   
   

Isisombululo

Ukuzalisa ubhaka walo ngamanzi, idada linesisombululo esinye kuphela: kufuneka liwufake umlomo walo ngokunzulu nangokunzulu kwichibi leentlanzi kwaye litye intlanzi de onke amanzi asesiswini salo adluliselwe kubhaka.

Xa idada lirhweba ngomlomo walo , omile okwe -isosceles ebomvu elingunxantathu wasekunene , kumphezulu we- X² , liginya umlinganiselo olinganayo wentlanzi - X² , egcinwe esiswini salo . Ekubeni isisu sele sizaliswe ngamanzi , intlanzi nganye engena ikhupha umthamo olinganayo wamanzi, okhutshwa ngokuvula kwi-backpack . (Umfanekiso 9)

Ngenxa yoko, i -backpack igcwalisa ngokuthe ngcembe ngamanzi, ngelixa ibhaluni yamanzi esiswini iyancipha ngokukhawuleza ububanzi.

Idada liyaqhubeka le nkqubo - lifaka umlomo walo echibini - de isisu salo sizaliswe ngokupheleleyo yintlanzi kwaye onke amanzi adluliselwe kwi-backpack, ukuphumeza ukulingana. (umfanekiso 9,10,11,12)

Emva kokutya intlanzi yokugqibela engena esiswini salo, idada lethu liginye iyonke 9.7X² iintlanzi , likwazi ukukhupha wonke umthamo wamanzi esiswini salo, 9.7X² , kwaye liwugcine kubhaka.

Ngobhaka unomthamo opheleleyo we -18X² , ngoku izaliswe ukuya kuma -54% , izalisekisa iimfuno zemishini yayo yokugqibela! (Umfanekiso 13)

Ukufezekisa oku, idada kuqala liye lafumana izigaba ezi-6 zokukhula kwe-rectilinear kunye nokufana okufanayo ngaphakathi kwe- Matrix a - I-Duck , ifikelela kubude be -6X , kunye nesisu sayo esizaliswe ngamanzi sanda ukuya kwi-radius ye- 1.75X .

Emva koko, ngaphezu kwezinye izigaba ezi-6 , ngaphakathi kweMatrix b - Ichibi lentlanzi , idada kwafuneka lifake umlomo walo echibini lentlanzi ngokulinganayo kwi -angle ye-45-degree , ukuya kubunzulu be- h = 4.4X , ukulinganisa ukusuka entloko ukuya kwi-engile emazantsi. Obu bunzulu bubalelwa kwi -73% yobude bedama (6X) kwaye bufuna ukuba idada lidle i-54% (9.7X²) yetotali yabemi beentlanzi (18X²) echibini. (Umfanekiso 14)

Zonke ezi meko zahlangatyezwana nazo zavumela idada ukuba ligcwalise ngaphezulu kwe 50% yomthamo wobhaka ngamanzi , okulivumela ukuba lishiye i-matrix.

Kungabonakala kungakholeleki, kodwa yintoni ephambi kwakho - ii-isosceles ezimbini ezichanekileyo iinxantathu kunye nesangqa , ehlelwe kwii -matrices ezimbini ze-6x6 - imele isiseko semithetho yezemali eyenza ihlabathi lethu namhlanje. (Umfanekiso 17)

Nangona kunjalo, ukucacisa ngokupheleleyo kunye nokuqonda yonke ikhowudi , kufuneka sihlolisise i- Saint Nicholas Balloons Theorem - isakhelo sokuqala esityhila imigaqo engundoqo yemathematika exhasa ukusekwa kwazo zonke iimarike zemali.

Ithiyori yeebhaluni zikaNicholas

Ukususela ekuqaleni kweemarike zezemali, uluntu luye lwamiselwa ukuba lukholelwe ukuba umgca wetshathi yexabiso yisalathisi esiphezulu sexabiso.

Enyanisweni, owona mlinganiselo ubaluleke kakhulu awukho kumgca ngokwawo, kodwa kwindawo engaphantsi kwayo.

Ngokutsho kweBalloon Theorem, le ndawo izaliswe ngokuchanekileyo ngeebhaluni ezinobungakanani obahlukeneyo, ngamnye omele abagcini kunye nexabiso le-stack yabo.

Ngaphaya koko, ulungiselelo lwezi bhaluni kunye nentshukumo yazo imisela ngokupheleleyo ubume betshathi kunye nokuvela kwexabiso.

Imephu yebhaluni, iradiyasi yebhaluni

Ummandla webhaluni nganye (isangqa) unikwa yimveliso yobuninzi bempahla engomnini (n) kunye nexabiso le-asethi (p) - Isangqa = np . Umyinge wexabiso lokuthengisa ubalwa kumbindi webhaluni.

Kwangaxeshanye, ummandla wesangqa ubalwa kusetyenziswa ifomyula eqhelekileyo yemathematika Isangqa = πr².

Ngokulinganisa iiequations ezimbini, sinokufumana ifomula yeradiyasi yebhaluni.

Le fomyula yenza ukumelwa komnini ngamnye kunye nexabiso le-stake yabo njengesangqa, ukulinganisa indawo abahlala kuyo kwitshathi.

Oku kubonwayo kudala iBubble Map yabanini, apho onke amaqamza alungelelanisiwe kwaye abekwe ngobuchule phantsi kwetshati. (Umfanekiso 19)

Ifomula yokuwa

Intshayelelo

Yiba nomfanekiso-ngqondweni wetshathi yexabiso njengentambo eluhlaza ephumle kwingqokelela yeebhaluni ezinobukhulu obahlukeneyo, zonke zilungelelene ngokulinganayo.

Ukuba ibhaluni enkulu eluhlaza okwesibhakabhaka iyaphuma, intambo iya kuwela kwisithuba esishiywe yibhaluni eqhumayo, iphazamise isakhiwo sonke.

Oku kuphazamiseka kuya kukhokelela ngokwemvelo kwiibhaluni eziseleyo zizilungelelanise kwakhona de kufikelelwe imeko entsha yokulinganisela.

Yile ndlela kanye imodeli yobugcisa yayo nayiphi na itshathi yexabiso le-asethi isebenza ngayo. Iibhaluni zimele bonke abanini kunye nexabiso lee-stakes zabo, eziboniswe ngejometri njengezangqa phantsi kwetshathi. Xa umnini omkhulu ethatha isigqibo sokuba "akhuphe ibhaluni yakhe" (okt, ukurhoxisa ukuthengiswa kwemali ngokuthengisa izinto zakhe), ixabiso liyehla, lidala isithuba esilingana nesithuba ebesihlala kwibhaluni yomnini ngaphambili.

Ngenxa yemithetho yolondolozo, indawo yonxantathu obomvu i-ABC eyenziwe phantsi kwetshathi ngexesha lokuhla iya kufana nommandla webhaluni ekhutshweyo. Kule nto, sithatha umgama h , okanye ifomula yokuwa: h = 2.5r

Ifomula yokuwa

Ukuba i-stack enkulu ebanjwe ngumnini, emelwe ibhaluni ene-radius r phantsi kwetshathi, ihlanjululwe, ixabiso liya kuhla ngomgama we-h = 2.5r. Apha, u-h ulinganiswa ukusuka kweyona ndawo iphantsi yesiphatho sekhandlela ebonisa ukubuya umva. (Umfanekiso 22)

Igridi yeGrafu

Ukusebenzisa ifomula ye-Fall, sinokuqonda ukuba ixabiso liqhubela phambili ngezigaba ezintandathu ezilinganayo , zombini ngokuthe tye kunye ne-horizontal, xa uhlalutya isakhiwo setshathi.

Ngokukodwa, ishati yexabiso lomjikelo opheleleyo wempompo kunye nokulahla imelwe ngamatriki amabini e-6x6: enye ibamba i -uptrend kwaye enye ibonisa i -downtrend. Ngokudibeneyo, ezi matriki zenza isakhelo esilungeleleneyo esenza imephu yonke intshukumo yexabiso.

Ulwazi

Kubalulekile ukuqaphela ukuba iTheorem yeeBhaluni ijolise ngokukodwa kwindawo engaphantsi kwetshati yexabiso kwaye ifanelekile ngokukodwa kwiibhaluni ezinkulu (abanini abaneentlawulo ezinkulu). Uphononongo lujolise ikakhulu kumnini onebhaluni enkulu evumelekileyo kwitshathi (isangqa esibhalwe phantsi kwegrafu yexabiso) kunye neziphumo eziveliswa ngulo mnini. (Umfanekiso 24)

Ithiyori ijolise ekuboniseni ukuba, eneneni, umnini omnye oyintloko onebhaluni enkulu ulawula phantse zonke iimarike ezibalulekileyo, uququzelela ukuhamba kwemali enkulu, kwaye unefuthe kuqoqosho lwehlabathi.

Ukufumana ii-equations zokugqibela, iimeko ezifanelekileyo zentengiso zacingelwa: intshukumo yerectilinear kunye neyunifomu, i-angle ye-45-degree yeendlela, iimeko ezifanelekileyo zokungabi namali, kunye neemeko ezifanayo ezenziwe lula.

Ukuchaza iKhowudi yeDada

Ngoku ukuba sihlolisise i -Theorem ye-Balloon kwaye siyaqonda, ngokusebenzisa iifomyula ezicacileyo, indlela itshathi imodeli esekelwe ngayo kwiibhaluni ezingaphantsi kwayo, siya kuqhubela phambili kwi-decoding eyona nto iyimfihlo kunye nexabiso lemathematika ibali elibhaliweyo: Ikhowudi yeDuck .

Imatrix a - Idada

I-matrix yokuqala, ebizwa ngokuba yiDada , ayikho enye into ngaphandle kokubonakaliswa komjikelo opheleleyo we-uptrend, apho ixabiso le-asethi linyuka ngokulandelelana kunye ngokulinganayo kwizigaba ezi-6 ezilinganayo, kwi-angle ye-45 °. (Umfanekiso 25)

IDada

Isangqa esibhalwe kunxantathu simele isibambi esona sikhulu sivumelekileyo yitshati. Iqala ukuqokelela ii-asethi ukusuka ekuqaleni kwetshathi, ukwandisa isitaki sayo phakathi kwezigaba ezimbini zokuqala xa ixabiso le-asethi liphakathi kwe -0 kunye ne -2X , iqinisekisa ubuninzi bayo be-stack kwi- avareji yexabiso le -1X . (Umfanekiso 26)

Ukulinda

Emva kokuqinisekisa i-stack yayo ephezulu kwizigaba zokuqala, umnini omkhulu ulinda ngomonde de kube sekupheleni kwexabiso le -6 .

Ngokutsho kweTheorem yeBhaluni, ngoku singabala ngokuchanekileyo ukuba yeyiphi ipesenti yendawo ephantsi kwetshathi emele lo mphathi njengesangqa, kunye neziphumo eziveliswayo xa bethatha isigqibo sokuvala ibhaluni yabo.

Ewe, zininzi ezinye iibhaluni ezincinci phantsi kwetshathi ezigcwalisa indawo engezantsi, kodwa izibalo zethu zijolise kuphela kumdlali omkhulu. Unxantathu omthubi umele indawo engezantsi kwetshathi yexabiso - umzimba weDada.

Xa zonke izigaba ezintandathu zigqityiwe (umfanekiso 28,29) kwaye isangqa sifikelela kumaxabiso awona aphezulu, umnini omkhulu uyazi ukuba lixesha lokuqalisa ukucima ibhaluni kunye nokutshixa kwingeniso.

Imatrix b - Ichibi leentlanzi

Ukuthengisa isixa esikhulu kangaka kwaye ufikelele elona xabiso liphezulu le-avareji, umdlali omkhulu kufuneka athengise ngokuthe chu kwaye ngokulinganayo ngaphezulu kwezigaba ezi-5.

Yilapho i-matrix yesibini, i-Fish Pond , ingena khona. Imele umjikelo webhere opheleleyo, wehla ngokulinganayo kwi-angle ye-45 ° ukusuka phezulu ukuya kwindawo yokulinganisa okanye inkxaso - apho ixabiso lizinzile xa ukupheliswa kwebhaluni enkulu kugqityiwe. (umfanekiso 30,31)

Ngenxa yemithetho yolondolozo evela kwiBalloon Theorem, njengoko ububanzi bebhaluni buyancipha (oko kukuthi, umnini omkhulu uthengisa izinto zabo), unxantathu ongezantsi kwetshathi ye-downtrend uya kwandiswa ngokulinganayo (oko kukuthi, ixabiso liya kuhla ngokulinganayo) kude kube sekupheleni, xa indawo yonxantathu obomvu phantsi kwe-downtrend ilingana nommandla wesangqa esibhaliweyo. (umfanekiso 31,32,33,34,35)

Iziphumo zokugqibela:

1. Ukuqokelela kokuqala : Umdlali ufumana ubuninzi be-asethi ngexesha lezigaba ezimbini zokuqala ngexabiso eliqhelekileyo le- 1X .
2. Isicwangciso seNzuzo : I-stack yonke ihlanjululwe ngaphezu kwezigaba ezintlanu ngexabiso eliphakathi kwe -1.75X , enqunywe ngumbindi wesangqa esibanjwe ngaphantsi kwetshathi. Oku kubangela inzuzo encinci ye- 75% ekupheleni komjikelo.
3. Ubungakanani bebhaluni : Ukufezekisa oku, umdlali ugcina ibhaluni phantsi kwetshati eneradiyasi ye -1.75X kuwo wonke umjikelo.
4. I-Sell-Off Point : Ukutshatyalaliswa kuqala ngexabiso le -6X , ebonisa ukuqala kwe-downtrend.
5. Impembelelo yokuhla kweXabiso : Emva kokuba isitakhi esikhulu siphelisiwe, ixabiso liyehla ukuya kwindawo elinganayo, umgama we- h = 4.4X ukusuka "kwintloko yedada". Oku kubangela ukuhla kwexabiso nge-73%, kubalwa ukusuka kwintloko yeDada ukuya kwindawo elinganayo.
6. Uyilo lweNkqubo kunye noLawulo : Le nkqubo yemathematika yayiyilwe ngenjongo yokulungelelanisa zonke iimarike ezinkulu zehlabathi. Kukholelwa ukuba ilawulwa ngumntu omnye, ekusenokwenzeka ukuba uququzelele iimarike zemali ukusukela ekusekweni kwazo. Lo mntu waziwa njengeDada .

Ngoko ke imbali iya kukhumbula

Ukukhumbula lo mzuzu wembali-ukuphulwa kwekhowudi ebaluleke kakhulu kwimbali yanamhlanje - ndenze i-meme coin kwiinyanga ezimbini ezidlulileyo kwi-pump.fun, ebizwa ngokufanelekileyo The-Duck-Code .

Ngesakhelo sangoku esichazwe ngokupheleleyo, ixesha elitsha liyaqala-ithuba lokuba isizukulwana esilandelayo sabarhwebi siphakame kwaye sithathe umngeni. Kule minyaka ilishumi izayo, uthumo lwabo luya kuba kukutyhila isakhelo esisisiseko esisombulula ezi mpazamo zibalulekileyo kwaye sithintele iinkqubo zezimali ekuqhubeni uluntu lufikelele ebukhobokeni bokugqibela. Njengoko imile, ngaphezu kwe-95% yabathengisi balahlekelwa ngaphakathi kwenkqubo yangoku.

Ngalo mzuzu ubalulekileyo, unjingalwazi ukushiya nomyalezo osuka entliziyweni: Wanga uThixo angakusikelela ngobulumko, ukulunga, kunye nombono wokwenza indlela engcono. Kuba ekugqibeleni, ezi zizinto ezibaluleke ngokwenene.

Ngenxa yesi sikhokelo siyilwe ngabom, esinika oyena mdlali ubalaseleyo ulawulo phezu komdlalo, sinokubona iinxaxhi ukusuka kwipateni "eyiyo" yokumpompa kunye nokulahla yeDada kwiitshathi zehlabathi lonke, elibonakala ngalo lonke ixesha-ukusuka kumzuzu om-1 ukuya kwinyanga enye. .

Nangona kunjalo, i -The-Duck yokwenyani , enye kwaye kuphela, ayinakufunyanwa lula. Ihlala kude, kowona lwandle lunzulu nolona luthe qelele, ihamba ithe cwaka ebumnyameni apho amanzi akhoyo mkhulu. Apha, izenzo zayo zidlala ngamaxesha amakhulu kakhulu, anje ngeveki okanye ngenyanga.

I -THE-Dada yokwenyani ikhona kuzo zonke iimarike ezinkulu zemali, i-orchestrating movements on a grand scale.

Okubangel 'umdla kukuba, i -THE-Duck yokwenyani inokujongwa kwiimarike ezintsha, ezincinci ezinokubakho okuphezulu, njengemarike yeBitcoin .

Ukuchonga apho iDada lokwenyani lenze khona, landela la manyathelo:

1. Gxininisa kwiimarike ezinkulu kunye neetshathi zeveki: Jonga iimakethi ezinkulu ezinobutyebi obubalulekileyo.
2. Fumana umjikelo opheleleyo wempompo kunye nokulahla: Chonga umjikelezo opheleleyo, ukususela ekuqaleni kwe-uptrend ukuya kwi-downtrend yokugqibela.
3. Yahlula itshathi ibe sisiqingatha: Zoba umgca othe nkqo ukusuka kwincopho yexabiso, uphawula inqaku lokubuyela umva.
4. Beka unxantathu wasekunene we-isosceles phantsi kwetshathi: Unxantathu kufuneka ulungelelene phantsi kwecandelo le-uptrend yetshathi, uqinisekise ukuba izibane aziyi kungena kunxantathu kakhulu. Imijikelo emikhulu ibalulekile.
5. Lungelelanisa i-vertex ephezulu kanxantathu ("iNtloko yeDada") kunye nekhandlela eliphakamileyo: Indawo ephezulu kanxantathu kufuneka ilungelelaniswe nelona xabiso liphezulu ikhandlela kodwa akufanele lidlule kuyo.
6. Bala indawo elinganayo: Ukusuka kwi-vertex ephezulu kanxantathu, linganisa ukuhla kwexabiso malunga ne- 75% (okanye 3/4) . Zoba umgca othe tye kweli nqanaba ukuseka indawo yolingano .

Lo mmandla wolungelelwaniso umele ibhalansi yexabiso lokwenyani, eliya kuthi ekugqibeleni lifikelelwe kwaye lisebenze njengenkxaso enkulu emva kokuba umdlali obalaseleyo ebhangisile isitaki sakhe sonke.

Kumjikelo ngamnye kule mijikelezo mikhulu, iDada -umdlali obalaseleyo-irhoxisa ubuncinci be -53% yemali yokuhlawula amatyala eyongezwe ngabathathi-nxaxheba abancinci. Ekupheleni komjikelo, baqinisekisa inzuzo ye -75% kutyalo-mali lwabo lulonke.

Eli qhinga lisebenza ngomlinganiselo omkhulu, ngokufuthi libandakanya iitriliyoni zeerandi. IDada ibisenza esi sikhokelo ukusukela ekusekweni kweemarike zemali, ngokwenza le khowudi yongamele imijikelo yemali yokuhlawula amatyala.
