Promoting Semantics in Multi-objective Genetic Programming based on Decomposition

no code implementations8 Dec 2020 Edgar Galván, Fergal Stapleton

The study of semantics in Genetic Program (GP) deals with the behaviour of a program given a set of inputs and has been widely reported in helping to promote diversity in GP for a range of complex problems ultimately improving evolutionary search.

Semantic-based Distance Approaches in Multi-objective Genetic Programming

no code implementations25 Sep 2020 Edgar Galván, Fergal Stapleton

We empirically and consistently show how by naturally handling semantic distance as an additional criterion to be optimised in MOGP leads to better performance when compared to canonical methods and SSC.
