Evolutionary Computation for Dynamic Complex Systems

Overview

Developing evolutionary algorithms that can track moving optima and adapt to changing environments in real-time decision-making scenarios.

Key Questions

  • How can populations maintain sufficient diversity to adapt to unpredictable environmental changes?
  • What strategies can effectively detect and respond to different types of environmental changes?
  • How can we balance exploration and exploitation in time-varying landscapes?

Our Contributions

  • Systematic study of transfer learning in dynamic multiobjective optimization
  • Spatial-temporal knowledge transfer for dynamic constrained problems
  • Knee point-based approaches for handling imbalanced transfer
