Speeding-up Evolutionary Algorithms to solve Black-Box Optimization Problems

1 code implementation23 Sep 2023 Judith Echevarrieta, Etor Arza, Aritz Pérez

However, these algorithms require a large number of evaluations to provide a quality solution, which might be computationally expensive when the evaluation cost is high.

Generalized Early Stopping in Evolutionary Direct Policy Search

1 code implementation7 Aug 2023 Etor Arza, Leni K. Le Goff, Emma Hart

We test the introduced stopping criterion in five direct policy search environments drawn from games, robotics and classic control domains, and show that it can save up to 75% of the computation time.

Comparing Two Samples Through Stochastic Dominance: A Graphical Approach

1 code implementation15 Mar 2022 Etor Arza, Josu Ceberio, Ekhiñe Irurozki, Aritz Pérez

Non-deterministic measurements are common in real-world scenarios: the performance of a stochastic optimization algorithm or the total reward of a reinforcement learning agent in a chaotic environment are just two examples in which unpredictable outcomes are common.
