A template is presented that captures a vast majority of the local sea
rch algorithms proposed in the literature, including iterative improve
ment, simulated annealing, threshold accepting, tabu search and geneti
c algorithms. The template leads to a classification of existing local
search algorithms and offers the possibility to fit in new types of l
ocal search approaches. (C) 1998 Published by Elsevier Science Ltd. Al
