Evolutionary approaches

Definition

Evolutionary approaches refer to a set of optimization techniques inspired by the principles of natural selection and evolution. These methods use mechanisms such as mutation, selection, and recombination to iteratively improve solutions to complex problems, making them particularly suitable for multi-task scenarios where diverse objectives must be addressed simultaneously.
