چکیده

In this paper, we show how an Extended Guided Local Search can be applied to the Quadratic Assignment Problem and show the extensions can improve its performance. GLS is a general, penalty-based meta-heuristic, which sits on top of local search algorithms, to help guide them out of local minima. GLS has been shown to be successful in solving a number of practical real life problems, such as the travelling salesman problem, BT’s workforce scheduling problem, the radio link frequency assignment problem, the SAT problem, the weighted MAX-SAT problems, and the vehicle routing problem. We present empirical results of applying several extended versions of Guided Local Search to the Quadratic Assignment Problem, and show that these extensions can improve the range of parameter setting within which Guided Local Search performs well. Finally, we compare the results of running our Extended Guided Local Search with some state of the art algorithms for the QAP.

Guided Local Search

Guided Local Search (GLS) is an intelligent search scheme for combinatorial optimization problems. A main feature of the approach is the iterative use of local search. Information is gathered from various sources and exploited to guide local search to promising parts of the search space. The application of the method to the Travelling Salesman Problem and the Quadratic Assignment Problem is exa...

Estimation of Distribution Algorithm with 2-opt Local Search for the Quadratic Assignment Problem

This chapter proposes a combination of estimation of distribution algorithm (EDA) and the 2-opt local search algorithm (EDA/LS) for the quadratic assignment problem (QAP). In EDA/LS, a new operator, called guided mutation, is employed for generating new solutions. This operator uses both global statistical information collected from the previous search and the location information of solutions ...
