WebSep 11, 2024 · Selecting features is an NP-Hard problem. The optimal configuration is a set or subset of those features, given a set of features. This method is a discrete selection. With a permutation of possibilities, it is very costly to determine the optimal feature set. Genetic algorithms use an approach to determine an optimal set based on evolution.
