Evolutionary Algorithms and Their Real-World Applications

Dear Colleagues,

Evolutionary algorithms have been successfully used to address complex real-world problems. For a large set of domains, they can calculate or approximate solutions within a reasonable time. There exist many successful optimization applications that are drawn from the field of genetic algorithms, especially in combinatorial optimization applications, as well as from the need to evolve patterns and structures. These have highly multimodal search landscapes. Evolution strategies often show their strengths in terms of efficiency and adaptability in parameter optimization problems, such as in the issue of simulation-based optimization. Genetic programming, especially symbolic regression applications based on tree-based representation, is becoming increasingly important in the field of explainable and interpretable AI due to its unique ability to learn complex relationships in an interpretable form.

A current drawback of the evolutionary algorithms applied in the real-world is their tendency to be very domain-specific and to suffer from a high problem dependency, based on the no-free-lunch theorem. In order to overcome these limitations and enhance the efficiency and applicability of evolutionary algorithms in real-world scenarios, several approaches have been suggested, leading to the design of self-adaptive algorithms. These suggested methods including the extension of basic algorithms through the analysis of the topology and features of search spaces. Hybridization, local search, and specialized operators are also promising approaches that could lead to the development of even more efficient algorithms in terms of computational effort and solution quality. Moreover, the recent improvement in computational power and the successful implementation of advanced parallel and grid computing concepts have improved the efficiency of solving these problems.

This Special Issue aims to present the latest advances in the real-world applications of evolutionary algorithms. The scope of this Issue encompasses a broad range of topics, including new theoretical developments, innovative techniques, novel applications, and real-world optimization benchmarks, both with and without constraints. Suggested topics for papers include, but are not limited to:

• Theory and applications of genetic algorithms, evolution strategies and genetic programming;
• Hybrid approaches to real-world applications;
• Surrogate-assisted optimization and Bayesian optimization
• Multi-fidelity optimization;
• Simulation-based and evolutionary optimization;
• Application of simulation-based soft computing;
• Applications in combinatorial optimization, bio- and medical informatics, networks and telecommunications, logistics, scheduling, and transportation prescriptive analytics.
