20th European Conference on Evolutionary Computation in Combinatorial Optimization, EvoCOP 2020, held as part of Evostar 2020:20th European Conference, EvoCOP 2020, Held as Part of EvoStar 2020, Seville, Spain, April 15–17, 2020, Proceedings

The proceedings contain 14 papers. The special focus in this conference is on Evolutionary Computation in Combinatorial Optimization. The topics include: MILPIBEA: Algorithm for Multi-objective Features Selection in (Evolving) Software Product Lines; a Group Genetic Algorithm for Resource Allocation in Container-Based Clouds; the Local Optima Level in Chemotherapy Schedule Optimisation; genetic Programming with Adaptive Search Based on the Frequency of Features for Dynamic Flexible Job Shop Scheduling; an Algebraic Approach for the Search Space of Permutations with Repetition; a Comparison of Genetic Representations for Multi-objective Shortest Path Problems on Multigraphs; the Univariate Marginal Distribution Algorithm Copes Well with Deception and Epistasis; a Beam Search Approach to the Traveling Tournament Problem; Cooperative Parallel SAT Local Search with Path Relinking; dynamic Compartmental Models for Large Multi-objective Landscapes and Performance Estimation; fitness Landscape Analysis of Automated Machine Learning Search Spaces; On the Combined Impact of Population Size and Sub-problem Selection in MOEA/D.
