The IEEE Congress on Evolutionary Computation (CEC) is one of the largest and most important conferences within Evolutionary computation (EC), the other conferences of similar importance being Genetic and Evolutionary Computation Conference (GECCO), Parallel Problem Solving from Nature (PPSN) and European Conference on Genetic Programming (EuroGP).

CEC, which is organized by the IEEE Computational Intelligence Society in cooperation with the Evolutionary Programming Society, covers most subtopics of EC, such as Evolutionary robotics, Multiobjective optimization, Evolvable hardware, Theory of evolutionary computation, Evolutionary design etc. Papers can also be found that deal with topics which are related to rather than part of EC, such Ant colony optimization, Swarm intelligence and Quantum computing.
