New analysis improves genetic algorithm runtime for multi-valued functions

Researchers have improved the runtime analysis of a multi-valued compact genetic algorithm (cGA) applied to the G-OneMax function. The new analysis achieves a runtime of O(n r log^3(n) log^3(r)), a significant improvement over the previous O(n r^3 log^2(n) log(r)). This enhanced bound, which matches existing results for simpler multi-valued functions, was demonstrated using advanced drift theorems and concentration inequalities to track probability mass movement within the algorithm's frequency matrix.

    Runtime Analysis of a Compact Genetic Algorithm on a Truly Multi-valued OneMax Function

    Recently, the runtime analysis of multi-valued estimation-of-distribution algorithms in the framework of Ben Jedidia et al. (TCS 2024) has made significant advancements. However, almost all existing analyses are limited to multi-valued objective functions that in each dimension o…
