It is widely believed that the power-law is a proper probability distribution being effectively applied for evolution in τ-EO (extremal optimization), a general-purpose stochastic local-search approach inspired by self-organized criticality, and its applications in some NP-hard problems,...

The adjustable parameters of probability distributions adopted by extremal optimization (EO) and its modified versions play a critical role in controlling their performances. Unlike the traditional static probability distribution based strategy, this paper presents a novel method called...
