    Harmony search (HS) algorithm is relatively a recent metaheuristic optimization
    method inspired by natural phenomenon of musical improvisation process.
    despite its success, the main drawback of harmony search are contained in its tendency
    to converge prematurely due to its greedy selection method. This probably
    leads the harmony search algorithm to get stuck in local optima and unsought solutions
    owing to the limited exploration of the search space. The great deluge algorithm
    is a local search-based approach that has an efficient capability of increasing
    diversity and avoiding the local optima. This capability comes from its flexible
    method of accepting the new constructed solution. The aim of this research is to
    propose and evaluate a new variant of HS. To do so, the acceptance method of the
    great deluge algorithm is incorporated in the harmony search to enhance its convergence
    properties by maintaining a higher rate of diversification at the initial stage of
    the search process. The proposed method is called Harmony Search Great Deluge
    (HS-GD) algorithm. The performance of HS-GD and the classical harmony search
    algorithm was evaluated using a set of ten benchmark global optimization functions.
    In addition, five benchmark functions of the former set were employed to compare
    the results of the proposed method with three previous harmony search variations
    including the classical harmony search. The results show that HS-GD often outperforms
    the other comparative approaches.

    ABSTRACT Genetic algorithm (GA) is a heuristic search technique that draws inspiration from principles and mechanisms of natural selection. Conventionally, parents selection takes place at every generation and offspring are reproduced through genetic operators like crossover and mutation. The process reiterates until some termination conditions are met. Until recently, little attention has been paid on the enduring relationship between parent solutions. In this paper, we take on and further extend the idea of monogamous genetic algorithm to solving real-coded numerical optimization problems. In this GA model, each monogamous pair of parents yields two offspring, and only the best two offspring survive into the next generation. Occasional infidelity generates variety and promotes diversity in the population. Simulation results over the IEEE-CEC’13 (IEEE Congress on Evolutionary Computation 2013) contest for real parameter single objective optimization with 28 benchmark functions demonstrate the effectiveness of the proposed approach.
