Multiple trials is the basic concept of many parallel simulated annealing. It is to perform multiple trials at the same time to search acceptable solutions. The division simulated annealing with no communication and The clustering simulated annealing are two common types of parallel simulated annealing methods. The division simulated annealing with no communication makes each processor generate its own adjacent solution from its own current solution and compute the acceptance probability for a adjacent solution. Each of the processors searches solutions without communicating each other. Clustering simulated annealing makes each processor generate its own adjacent solution from a common current solution and compute the acceptance probability for each adjacent solution. Then, it decides which adjacent solution should be used to replace current solution according to a pre-specified rule.
许多平行模拟退火法之理论依据为多向试验,利用同一时间探索更多方向的试验来拓展搜寻的广度或深度,不进行沟通的分工模拟退火法(the division simulated annealing with no communication)以及丛集模拟退火法(the clustering simulated annealing)皆为平行化的模拟退火法,前者定义为各个处理器针对各自的起始解进行搜寻,产生各自的搜寻序列,在搜寻过程中处理器不进行任何沟通,各处理器仅针对自身之目前解进行搜寻;而后者定义为让所有处理器针对同一目前解进行运算搜寻各自的可能解,并各自决定其产出解之接受机率,最后根据事先决定之规则进行沟通比较,挑选其中一个可接受解取代目前解。
