New theory on (1+1) EA expected hitting time sensitivity

By PulseAugur Editorial · [1 sources] ·

This paper delves into the theoretical underpinnings of evolutionary algorithms, specifically the (1+1) EA with standard bit mutation. Researchers explore the sensitivity of expected hitting times to mutation rates, introducing novel concepts like per-state sign theorems and verifiable certificates for non-lumpable families. The study highlights a formalization pitfall regarding the Margulis-Russo formula and presents exact separations to demonstrate that one-step success-rate quantities do not fully determine expected hitting times.

    Signed Sensitivity of Expected Hitting Time to Mutation Rate in the (1+1) EA: Per-State Sign Theorems and Verifiable Certificates for Non-Lumpable Families

    For the (1+1) evolutionary algorithm with standard bit mutation, we study the sensitivity of the expected hitting time $H_p=\mathbb{E}_x T$ to the mutation rate. We first point out an easily overlooked formalization pitfall: the improvement event is not monotone in the mutation m…
