This study combines stochastic learning automata and genetic algorithms (GAs) to accelerate convergence and escape local optima in optimization. The novel approach offers a clear stopping rule and bounds for real-valued function optimization.

Area of Science:

  • Computational intelligence
  • Optimization algorithms
  • Machine learning

Background:

  • Stochastic learning automata and genetic algorithms (GAs) possess global optimization capabilities.
  • Learning automata face criticism for slow convergence rates.
  • Existing methods may struggle to escape local optima effectively.

Purpose of the Study:

  • To enhance the convergence rate of learning automata using GAs.
  • To improve the ability of optimization algorithms to escape local optima.
  • To introduce a method for determining convergence and providing stopping rules in GAs.

Main Methods:

  • Integration of stochastic learning automata with genetic algorithms.
  • Separation of genotype and phenotype properties within the GA framework.
