Combining Forces to Solve the Car Sequencing Problem

Laurent Perron, Paul Shaw

Abstract: Car sequencing is a well-known difficult problem. It has resisted and still resists the best techniques launched against it. Instead of creating a sophisticated search technique specifically designed and tuned for this problem, we will combine different simple local search-like methods using a portfolio of algorithms framework. In practice, we will base our solver on a powerful LNS algorithm and we will use the other local search-like algorithms as a diversification schema for it. The result is an algorithm is competitive with the best known approaches.
