Wang, Zhao, Shen, and Konan (2017)developed an algorithm to enhance randomized wrapper performance by combining LW-index statistical measures with the Sequence Forward Search algorithm (SFS-LW). LW-index is a linear algorithm for assessing the subset of features in asupervised classificationproblem....

We present a randomized approximation algorithm for the problem of finding a subset of a finite vector set in the Euclidean space with the maximal norm of the sum vector. We show that, with an appropriate choice of parameters, the algorithm is polynomial for the problem with every fixed dimens...
Problem statement You are given a bipartite graph with nn vertices and mm edges. Each edge has a cost cece. You want to find the minimum cost perfect matching: each vertex on the left must be matched to exactly one vertex in the right and vice versa. The sum of the costs of the edge...

The whale optimization algorithm has received much attention since its introduction due to its outstanding performance. However, like other algorithms, the whale optimization algorithm still suffers from some classical problems. To address the issues of
