The 19th Learning and Intelligent Optimization Conference

The 19th Learning and Intelligent Optimization Conference (LION 2025) is a focused international forum dedicated to the synergies between machine learning and combinatorial optimization, exploring how learning algorithms can improve optimization and how optimization techniques can enhance learning systems. Topics include meta-heuristic design enhanced by machine learning, algorithm selection and configuration, hyper-heuristics, learning-based parameter tuning, and the application of intelligent optimization to logistics, scheduling, engineering design, and computational biology.

LION attracts researchers from operations research, evolutionary computation, AI, and machine learning who share the conviction that the boundary between learning and optimization is artificial and that crossing it leads to more powerful methods. The conference is valued for its interdisciplinary spirit and for its emphasis on empirical rigor in algorithm evaluation, attracting both theoreticians studying the mathematical properties of learning-enhanced optimization and practitioners who need principled methods for tuning and selecting algorithms for real-world problems.
