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.

在高复杂性-在NK景观的决定的组成元素之间的普遍相互依赖性-我们的算法获得健身优于现有的研究报告。我们将组成决策的决策元素分布到聚类中。当考虑决策元素的值的变化时,如果位于决策元素旁边的集群成员的聚合适合度较高,则进行向前移动。选择路径中具有最高适应度的决策配置。增加聚类的数量可以获得更高的适应度。此外,在集群中实现包括多达两个变化的移动也获得更高的适应度。我们的算法通过更广泛的搜索获得更好的结果,允许检查更远的配置。为了纪念查尔斯·林德布洛姆(Charles Lindblom),我们将这种算法命名为“得过且过算法”(muddling through algorithm),他在复杂的计算机模拟出现之前很久就发现了这一过程的有效性。

理解系统如何被设计成可进化的是优化、进化和复杂系统科学研究的基础。因此,许多研究人员已经认识到可进化性的重要性,即在生物进化和演化计算领域中发现更高适应度的新变体的能力。Ciliberti等人(Proc.Nat.Acad.科学,2007)和Wagner(Proc. R. Soc. B.,2008)提出了一个潜在的重要联系之间的鲁棒性和系统的可进化性。特别是,有人认为,鲁棒性实际上可能导致进化的出现。在这里,我们研究了两个设计原则,冗余和退化,实现鲁棒性,我们表明,他们有一个显着不同的影响系统的演化。特别是,纯冗余系统被发现有很少的进化,而系统退化,即分布式鲁棒性,可以是数量级更进化。这些结果提供了深入了解的一般原则,实现进化,并可能被证明是一个重要的一步,在追求进化表示演化计算。
