Weighted Coloring: Further Complexity and Approximability Results
Given a vertex-weighted graph G = (V, E; w), w(v) ≥ 0 for any v ∈ V , we consider a weighted version of the coloring problem which consists in finding a partition S = (S1, . ...

Lagrangean relaxation with clusters and column generation for the manufacturer's pallet loading problem
We consider in this paper a new lagrangean relaxation with clusters for the Manufacturer’s Pallet Loading Problem (MPLP). The relaxation is based on the MPLP formulated as a Max...
