摘要

本文在Rosenbrock、Rastrigin和Ackley三种经典基准函数上比较了多混沌系统在优化过程中的发展。多混沌系统涉及基于离散混沌映射的五种不同随机化(Burgers、Delayed Logistic、耗散、Lozi和Tinkerbell),并根据优化任务的发展调整其选择的概率。为了模拟自适应对随机化概率调整过程的影响,采用了两种不同的差分进化算法。第一种非自适应变体是采用rand/1突变策略的DE,第二种自适应变体是基于成功历史的新型自适应DE (SHADE)。

Simulating the Effect of Adaptivity on Randomization
This paper compares the development of multi-chaotic system during the optimization process on three classical benchmark functions – Rosenbrock, Rastrigin and Ackley. The multi-chaotic system involves five different randomizations based on discrete chaotic maps (Burgers, Delayed Logistic, Dissipative, Lozi and Tinkerbell) and the probability of their selection is adjusted according to the development of the optimization task. Two variants of Differential Evolution (DE) are used in order to simulate the effect of adaptivity on the randomization probability adjustment process. First non-adaptive variant is DE with rand/1 mutation strategy and the second adaptive variant is novel Success-History based Adaptive DE (SHADE).
