Evolutionary Computation in Dynamic and Uncertain Environments

General Introduction

Many real-world optimization problems are subjected to dynamic and uncertain environments that are often impossible to avoid in practice. For instance, the fitness function is uncertain or noisy as a result of simulation/measurement errors or approximation errors (in the case where surrogates are used in place of the computationally expensive high fidelity fitness function). In addition, the design variables or environmental conditions may also perturb or change over time. For these dynamic and uncertain optimization problems, the objective of the evolutionary algorithm is no longer to simply locate the global optimum solution, but to continuously track the optimum in dynamic environments, or to find a robust solution that operates optimally in the presence of uncertainties. This poses serious challenges to conventional evolutionary algorithms.

Handling dynamic and uncertain optimization problems in evolutionary computation has received an increasing research interests over the recent years. A variety of methods have been reported across a broad range of application backgrounds. Topics of interest include but are not limited to:

  • Benchmark problems and performance measures
  • Tracking moving optima
  • Dynamic multi-objective optimization
  • Adaptation, learning, and anticipation
  • Handling noisy fitness functions
  • Using fitness approximations
  • Searching for robust optimal solutions
  • Comparative studies
  • Hybrid approaches
  • Theoretical analysis
  • Real-world applications
