Escaping Local Optima using Crossover with Emergent or Reinforced Diversity

2016 · White Rose Research Online (University of Leeds, The University of Sheffield, University of York)

Population diversity is essential for avoiding premature convergence in Genetic Algorithms (GAs) and for the effective use of crossover. Yet the dynamics of how diversity emerges in populations are not well understood. We use rigorous …
Hybrid Selection Allows Steady-State Evolutionary Algorithms to Control the Selective Pressure in Multimodal Optimisation

2025 · Proceedings of the Genetic and Evolutionary Computation Conference

Recent work has shown that Inverse Tournament Selection operators within steady-state evolutionary algorithms (EAs) allow to control the selective pressure much more accurately than in generational EAs. However, to achieve low selective pressures, large tournament …
