Abstract
Tabu search as proposed by Glover [3,4] has proven to be a very effective metaheuristic for hard problems. In this paper we propose that hash functions be used to record the solutions encountered during recent iterations of the search in a long list. Hash values of potential solutions can be compared to the values on the list for the purpose of avoiding cycling. This frees the algorithm designer of the need to consider cycling when creating tabu restrictions based on move attributes. We suggest specific functions that result in very good performance.

Paper: Robust taboo search for the quadratic assignment problem

TL;DR: An adaptation of taboo search to the quadratic assignment problem is discussed in this paper, which is efficient and robust, requiring less complexity and fewer parameters than earlier adaptations.
