The Bicriterion Multimodal Assignment Problem: Introduction, Analysis, and Experimental Results

Abstract: Abstract:We consider the bicriterion multimodal assignment problem, which is a new generalization of the classical linear assignment problem. A two-phase solution method using an effective ranking scheme is presented. The algorithm is valid for generating all nondominated criterion points or an approximation. Extensive computational results are conducted on a large library of test instances to test the performance of the algorithm and to identify hard test instances. Also, test results of the algorithm applied… Show more

“…And, it is NP-hard since the min-max regret assignment problem, as a special case of the assignment problem, is known to be NP-hard [47]. As one of the most-studied, well-known, and important problems of discrete optimization, the assignment problem has been well studied, and many algorithms have been designed to solve it, including single-objective and multiobjective cases [48][49][50].…”

“…If all objective functions map to the same set S, then we simply write S p . Surprisingly little research has been devoted to branch-and-bound algorithms for general BOCO problems although many problems can be fitted into this framework, for example the bi-objective knapsack problem (Ulungu and Teghem 1997), the bi-objective assignment problem (Przybylski et al 2008, Pedersen et al 2008, bi-objective facility location problems (Fernandez and Puerto 2003), and the bi-objective TSP (Bérubé et al 2009).…”
