PhD Research Topics in Population-based Metaheuristic Algorithms

Population-based Metaheuristic Algorithms are approaches that search for a near-optimal solution by maintaining a set of candidate solutions and using population features to iteratively guide the search.

These algorithms typically involve some form of randomization or probabilistic selection and use mechanisms like selection, crossover, and mutation to generate new candidate solutions from existing ones. Examples of a population-based metaheuristic algorithm

Advantages of a population-based metaheuristic algorithms

There are several advantages of using population-based metaheuristic algorithms in optimization problems, including:
 •  Global optimization: Population-based metaheuristics can find the global optimum solution in many problems rather than getting stuck in local optima.
 •  Robustness: Due to their probabilistic nature and the maintenance of a population of solutions, population-based metaheuristics are relatively robust to the choice of initial conditions and small perturbations in the problem.
 •  Flexibility: Population-based metaheuristics can handle a wide range of optimization problems, including those with non-linear, discontinuous, and multimodal objective functions.
 •  Simplicity: The basic mechanisms of population-based metaheuristics are simple to understand and implement, making them accessible to practitioners with limited optimization backgrounds.
 •  Parallelism: These algorithms are well-suited to parallel implementation, as each candidate solution can evolve independently.
