Faster Optimization Through Genetic Drift

no code implementations18 Apr 2024 Cella Florescu, Marc Kaufmann, Johannes Lengler, Ulysse Schaller

For the classical benchmark OneMax, the cGA has to two different modes of operation: a conservative one with small step sizes $\Theta(1/(\sqrt{n}\log n))$, which is slow but prevents genetic drift, and an aggressive one with large step sizes $\Theta(1/\log n)$, in which genetic drift leads to wrong decisions, but those are corrected efficiently.

Hardest Monotone Functions for Evolutionary Algorithms

1 code implementation13 Nov 2023 Marc Kaufmann, Maxime Larcher, Johannes Lengler, Oliver Sieberling

Recently, Kaufmann, Larcher, Lengler and Zou conjectured that for the self-adjusting $(1,\lambda)$-EA, Adversarial Dynamic BinVal (ADBV) is the hardest dynamic monotone function to optimize.

OneMax is not the Easiest Function for Fitness Improvements

1 code implementation14 Apr 2022 Marc Kaufmann, Maxime Larcher, Johannes Lengler, Xun Zou

In this paper we disprove this conjecture and show that OneMax is not the easiest fitness landscape with respect to finding improving steps.

Self-adjusting Population Sizes for the $(1, λ)$-EA on Monotone Functions

1 code implementation1 Apr 2022 Marc Kaufmann, Maxime Larcher, Johannes Lengler, Xun Zou

Recently, Hevia Fajardo and Sudholt have shown that this setup with $c=1$ is efficient on \onemax for $s<1$, but inefficient if $s \ge 18$.

Projection Bias in Effort Choices

Finally, when they have either increasing or decreasing productivity, people work less each day than previously planned.

Narrow Bracketing in Work Choices

1 code implementation12 Jan 2021 Francesco Fallucchi, Marc Kaufmann

Many important economic outcomes result from cumulative effects of smaller choices, so the best outcomes require accounting for other choices at each decision point.
