A number of readers have provided comments to suggest additional “Principles” for Courtship Algorithms. These comments have added further intriguing refinements to this new class of metaheuristic strategies.
You are invited to vote on your three favorites. Authors of the three selections that receive the most votes will be awarded a prize.
Each principle below is first stated in the context of human courtship, followed by the corresponding concept expressed as a metaheuristic strategy.
