New research analyzes EA performance in dynamic environments

By PulseAugur Editorial · [2 sources] ·

Two new research papers explore the performance of evolutionary algorithms (EAs) in dynamic environments. The first paper analyzes the (1+1)-EA on dynamic linear environments, proving a sharp threshold in mutation rate that dictates whether optimization time is polynomial or exponential. The second paper focuses on the (μ+1) EA for the Binary Value (BinVal) function, establishing a significantly improved runtime bound that shows it is only logarithmically slower than on the OneMax function.

    The $(1 + 1)$-EA in Dynamic Environments

    We study the $(1 + 1)$-EA in dynamic linear environments, where in every generation selection is performed with respect to a freshly sampled linear function with positive weights. We consider the Dynamic Binary Value problem, where each generation uses a uniformly random permutat…

    Improved Runtime Bound for the $(μ+ 1)$ EA on BinVal

    We study the $(μ+1)$ EA on the Binary Value function BinVal. We show that it needs at most $O(μ\log μ\cdot n \log n)$ function evaluations to find the optimum when $μ= o(n/\log n)$. This substantially improves upon the recent upper bound of $O(μ^5 n \log(n/μ^4))$ by Krejca, Neuma…
