Fast Neighborhood Search Heuristics for the Colorful Bin Packing Problem: Conclusion and References
Too Long; Didn't Read
Our bin packing approaches have proven highly effective, achieving solutions close to optimal even in scenarios with numerous items. The success stems from the Two-by-Two heuristic's quality, efficient neighborhoods, and the strong relaxation properties of Gilmore and Gomory Formulation. These strategies collectively contribute to near-optimal solutions and are particularly useful in color-constrained bin packing scenarios.
