Researchers have identified that selecting representative points from a multiobjective optimization Pareto front is NP-hard for three objectives. However, they also demonstrated that the integral R2 indicator, a measure of Pareto front quality, is a monotone submodular set function. This property allows for a greedy approximation algorithm that can achieve at least a (1-1/e) fraction of the maximum possible R2 gap. The study also provides an implementation of this greedy approach, which has a worst-case running time of O(n^6). AI
