Abstract
Simulated annealing is a stochastic search method that uses a temperature
function to calculate the probability of transition from a low cost point to a high
cost solution. In the conventional simulated annealing, the temperature declines
constantly, providing the search with a higher transition probability in the
beginning of the search and lower probability toward the end of the search. In
this paper, we propose a modified simulated annealing method that uses an
adaptive cooling schedule that declines based on the number of consecutive
downward moves. The performance of this algorithm is favourably compared
with those of the literature and the results indicate that the algorithm is capable
of finding optimal or near optimal solutions in reasonably short computational
time.
