What is cooperative coevolution in Genetic Algorithms?
Updated May 16, 2026
Short answer
A GA approach where multiple subpopulations evolve different parts of a solution.
Deep explanation
Cooperative coevolution decomposes a complex problem into subcomponents, each evolved separately. Fitness is evaluated based on collaboration between subpopulations. This improves scalability for high-dimensional problems.
Real-world example
Neural network evolution where weights are evolved in groups.
Common mistakes
- Poor decomposition leading to weak cooperation.
Follow-up questions
- How is fitness evaluated?
- Difference from island model?
