Computational Intelligence

Computational Intelligence (CI) is a field of artificial intelligence (AI) focused on developing algorithms and systems that exhibit adaptive, intelligent behavior in complex and uncertain environments. CI methods are inspired by natural systems and often use heuristic or bio-inspired approaches to solve problems that are computationally infeasible for traditional deterministic algorithms.
