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.
