Special Issue Information

Dear Colleagues,

Evolutionary computing has become a focus of attention during the last decades. Many interesting biologically inspired methods have been proposed to solve a wide variety of complex optimization problems. This rapidly evolving field has made tackling new applications possible in different areas of science, engineering, finance, or economics.

Optimization is present in many real-life problems. Thanks to the capabilities of modern computer systems, researchers face new challenges that require innovative technologies that go beyond the current state-of-the-art methods. A large number of methods, ranging from genetic and evolutionary algorithms to bio-inspired and multi-objective optimization, swarm intelligence, or metaheuristics, permit the solution of many types of problems in multiple areas. It is necessary to improve traditional methods or to propose new algorithms in order to cope with such demands. Focusing on applications is important for driving progress in this discipline and for solving increasingly complex and time-consuming problems.

The aim of this Special Issue is to bring together original contributions on the latest theories and applications of evolutionary computing. Articles with solid theoretical and practical contributions and with a focus on innovative applications in different areas of science, engineering, and economics are welcome.

Stagnation at local optima represents a significant challenge in bio-inspired optimization algorithms, often leading to suboptimal solutions. This paper addresses this issue by proposing a hybrid model that combines the Orca predator algorithm with deep Q-learning. The Orca predator algorithm is an optimization technique that mimics the hunting behavior of orcas. It solves complex optimization problems by exploring and exploiting search spaces efficiently. Deep Q-learning is a reinforcement learning technique that combines Q-learning with deep neural networks. This integration aims to turn the stagnation problem into an opportunity for more focused and effective exploitation, enhancing the optimization technique’s performance and accuracy. The proposed hybrid model leverages the biomimetic strengths of the Orca predator algorithm to identify promising regions nearby in the search space, complemented by the fine-tuning capabilities of deep Q-learning to navigate these areas precisely. The practical application of this approach is evaluated using the high-dimensional Heartbeat Categorization Dataset, focusing on the feature selection problem. This dataset, comprising complex electrocardiogram signals, provided a robust platform for testing the feature selection capabilities of our hybrid model. Our experimental results are encouraging, showcasing the hybrid strategy’s capability to identify relevant features without significantly compromising the performance metrics of machine learning models. This analysis was performed by comparing the improved method of the Orca predator algorithm against its native version and a set of state-of-the-art algorithms. Full article
