Multi-objective optimization capabilities

Definition

Multi-objective optimization capabilities refer to the ability of optimization software to handle problems with more than one objective function, allowing for the simultaneous optimization of multiple competing criteria. This approach is crucial in real-world applications where trade-offs must be made between conflicting goals, such as minimizing costs while maximizing performance or satisfaction. Such capabilities enable decision-makers to analyze and evaluate different solutions effectively, leading to more informed and balanced decisions.
