Special Session Theme: Evolutionary computation (EC) is a powerful class of population-based optimization techniques for solving complex optimization problems. Unlike many conventional optimization methods, EC algorithms generally do not require strong assumptions on problem properties, such as differentiability, convexity, continuity, or explicit mathematical formulations. Owing to their flexibility, robustness, and global search capability, EC algorithms have been widely applied to scientific, engineering, industrial, and data-driven optimization tasks.
Over the past decades, extensive research has been devoted to improving the performance of EC algorithms. Representative efforts include the design of effective evolutionary operators, adaptive parameter control strategies, reliable selection mechanisms, diversity preservation schemes, and hybrid local search techniques. These advances have substantially enhanced the search efficiency and robustness of EC. Nevertheless, when dealing with large-scale, high-dimensional, dynamic, expensive, multimodal, multitask, or highly constrained optimization problems, purely evolutionary search may still suffer from slow convergence, insufficient exploitation of useful search information, and limited scalability.
Recently, learning-aided evolutionary computation (LEC) has attracted increasing attention as a promising paradigm for enhancing evolutionary optimization. The central idea of LEC is to acquire, represent, manage, and reuse useful knowledge extracted from optimization problems, candidate solutions, historical search behaviors, population distributions, environmental changes, or external data sources. By integrating learning mechanisms into the evolutionary process, LEC aims to improve population reproduction, guide search directions, accelerate convergence, maintain population diversity, and reduce computational cost. Various forms of knowledge have been explored in the EC community, including problem-specific knowledge, solution-distribution knowledge, evolutionary-state knowledge, surrogate-assisted knowledge, representation knowledge, transfer knowledge, and knowledge learned from machine learning models, including large language models.
Despite recent progress, LEC remains an emerging research area with many open challenges. First, the theoretical foundations of LEC are still underdeveloped, and rigorous analysis is required to better understand how learned knowledge affects convergence, diversity, population dynamics, and runtime behavior. Second, effective knowledge representation and management remain challenging, especially when the learned knowledge is noisy, partial, dynamic, task-dependent, or expensive to obtain. Third, balancing learning and evolution is a critical issue, as excessive reliance on learned knowledge may lead to premature convergence, while insufficient learning may fail to improve search efficiency. Fourth, there is considerable potential for developing novel LEC frameworks that are scalable, interpretable, adaptive, distributed, and applicable to complex real-world optimization scenarios.
This special session aims to provide a focused forum for researchers and practitioners working on the principles, algorithms, theoretical foundations, and applications of learning-aided evolutionary computation. The session welcomes original research contributions that investigate how knowledge can be effectively learned, represented, transferred, reused, and integrated into evolutionary search. It also encourages studies that develop new learning mechanisms, analyze the behavior of LEC algorithms, and demonstrate the practical impact of LEC on challenging real-world optimization problems.
