Pareto Co-evolution

Definition

Pareto co-evolution is an evolutionary strategy that focuses on optimizing multiple objectives simultaneously, using the concept of Pareto efficiency where no objective can be improved without worsening another. This approach allows for the development of diverse solutions in a competitive environment, leading to a rich set of viable candidates that can adapt and thrive in real-world scenarios. By emphasizing trade-offs among competing objectives, pareto co-evolution helps bridge the gap between simulations and practical applications.
