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...

Constraint Programming Models for Graceful Graphs
The problem of finding a graceful labelling of a graph, or proving that the graph is not graceful, has previously been modelled as a CSP. A new and much faster CSP model of the pro...

Distributed Constraints for Large-Scale Scheduling Problems
Many problems of theoretical and practical interest can be formulated as Constraint Satisfaction Problems (CSPs). The general CSP is known to be NP-complete; however, distributed m...

The Puzzle Layout Problem
We address the new problem of puzzle layout as a new application of awing. We present two abstract models of puzzles, permutation puzzles and cyclic puzzles, which can be modeled a...
