Enhanced Optimization with Composite Objectives and Novelty Pulsation

no code implementations7 Jun 2019 Hormoz Shahrzad, Babak Hodjat, Camille Dollé, Andrei Denissov, Simon Lau, Donn Goodhew, Justin Dyer, Risto Miikkulainen

This paper improves this approach further by introducing novelty pulsation, i. e. a systematic method to alternate between novelty selection and local optimization.

Enhanced Optimization with Composite Objectives and Novelty Selection

no code implementations10 Mar 2018 Hormoz Shahrzad, Daniel Fink, Risto Miikkulainen

An important benefit of multi-objective search is that it maintains a diverse population of candidates, which helps in deceptive problems in particular.
