Mariana A. Londe, Luciana S. Pessoa, Carlos E. Andrade, Mauricio G. C. Resende

This paper provides a detailed literature review of Biased Random-Key Genetic Algorithms (BRKGA), analyzing over 150 academic articles to synthesize knowledge on its diverse applications, framework modifications, and hybridization strategies. The review delineates key trends, recurring challenges, and identifies future research directions for this metaheuristic.

Key insights

  • BRKGA's fundamental strength lies in its problem-agnostic random-key encoding and decoder function, facilitating code reuse and rapid prototyping across diverse optimization problems.
  • Effective hybridization, especially with local search heuristics, is a critical factor for achieving high-performance BRKGA solutions in practical applications.
  • Balancing exploration and exploitation is managed through mechanisms like double elitism for fast convergence and diversity-enhancing operators (e.g., island models, shake) to prevent premature convergence.
