摘要

在分布式消息传递多处理器系统上，提出了一种与问题无关的通用并行模拟退火算法(SA)。研究了序列优化算法，给出了组合优化问题及其邻域结构的分类。考察了几种并行化方法，考虑了它们对各种类问题的适用性。对于不同类的典型代表，给出了良好的并行SA实现。提出了一种同时处理多条马尔可夫链并动态减少链数的并行SA算法。该方法采用并行自适应冷却方案，效果良好。所有的算法都是在OCCAM-2中在一个自由配置的转发器系统上实现的。对不同数量的处理器进行了测量，最多可达128个转发器。

A general purpose distributed implementation of simulated annealing

The authors present a problem-independent general-purpose parallel implementation of simulated annealing (SA) on distributed message-passing multiprocessor systems. The sequential algorithm is studied, and a classification of combinatorial optimization problems together with their neighborhood structures is given. Several parallelization approaches are examined, considering their suitability for problems of the various classes. For typical representatives of the different classes, good parallel SA implementations are presented. A novel parallel SA algorithm that works simultaneously on several Markov chains and decreases the number of chains dynamically is presented. This method yields good results with a parallel self-adapting cooling schedule. All algorithms are implemented in OCCAM-2 on a free configurable transputer system. Measurements on various numbers of processors up to 128 transputers are presented.<>
