概要
A new parallel annealing scheme, stepwise-overlapped parallel annealing, is proposed. This can provide a massive speedup using a multiprocessor system with a large number of processors. It decomposes the annealing process by means of Markov chains. The annealing scheme of the systolic algorithm proposed by the Aart et al. (1985) is improved. The improved annealing schedule keeps a good temperature profile even when a large number of processors are used. The communication pattern is also enhanced. The new parallel annealing algorithm is applied to floorplan design problems. Experimental results show that the new parallel annealing algorithm is highly effective for a large number of processors. The experimental results of the proposed algorithm are compared with those of other parallel annealing algorithms and the distributed genetic algorithm

Abstract: A new parallel annealing scheme, stepwise-overlapped
        parallel annealing, is proposed. This can provide a
        massive speedup using a multiprocessor system with a
        large number of processors. It decomposes the
        annealing process by means of Markov chains. The
        annealing scheme of the systolic algorithm proposed
        by the Aart et al. (1985) is improved. The improved
        annealing schedule keeps a good temperature profile
        even when a large number of processors are used. The
        communication pattern is also enhanced. The new
        parallel annealing algorithm is applied to floorplan
        design problems. Experimental results show that the
        new parallel annealing algorithm is highly effective
        for a large number of processors. The experimental
        results of the proposed algorithm are compared with
        those of other parallel annealing algorithms and the
        distributed genetic algorithm
