摘要:

本文介绍了健身云的概念,作为一种替代的方式来可视化和分析搜索空间比健身景观的地理概念。有人认为,健身云的概念克服了景观表示的几个不足之处。我们的分析是基于解的适应度和最近解的适应度之间的相关性,根据一些邻居。我们专注于本地搜索引擎的行为,如登山者,在著名的NK健身景观。在这两种情况下,健身与健身相关性被证明是有关的上位参数K。

英文摘要:

This paper introduces the concept of fitness cloud as an alternative way to visualize and analyze search spaces than given by the geographic notion of fitness landscape. It is argued that the fitness cloud concept overcomes several deficiencies of the landscape representation. Our analysis is based on the correlation between fitness of solutions and fitnesses of nearest solutions according to some neighboring. We focus on the behavior of local search heuristics, such as hill climber, on the well-known NK fitness landscape. In both cases the fitness vs. fitness correlation is shown to be related to the epistatic parameter K.
