Abstract: This article presents a new algorithm for combinatorial optimization based on the basic Tabu Search scheme named Adaptive Tabu Search (A-TS). The A-TS introduces a new, complex function for evaluation of moves. The new evaluation function incorporates both the aspiration criteria and the long-term memory. A-TS also introduces a new decision making mechanism, providing means for avoiding possible infinite loops. The performance of A-TS was measured by applying it to the Quadratic Assignment Problem. The experimental results are compared to published results from other authors. The data shows that A-TS performs favorably against other established techniques.
