Multi-start methods for combinatorial optimization

Martí, Rafael; Resende, Mauricio G.C.; Ribeiro, Celso C. - In: European Journal of Operational Research 226 (2013) 1, pp. 1-8

Multi-start methods strategically sample the solution space of an optimization problem. The most successful of these methods have two phases that are alternated for a certain number of global iterations. The first phase generates a solution and the second seeks to improve the outcome. Each...

An efficient implementation of a VNS/ILS heuristic for a real-life car sequencing problem

Ribeiro, Celso C.; Aloise, Daniel; Noronha, Thiago F.; … - In: European Journal of Operational Research 191 (2008) 3, pp. 596-611

The car sequencing problem consists in sequencing a given set of cars to be produced in a single day. We address one of the variants of this problem, in which the objective of minimizing the number of violations of assembly constraints has a stronger weight than the minimization of the number of...
