: This package includes the MATLAB code of the PORSS algorithm  for subset selection. It solves the subset selection problem by first reformulating it as a bi-objective optimization problem (optimizing the given criterion and reducing the subset size simultaneously) and then employing a bi-objective evolutionary algorithm with both mutation and recombination. PORSS improves our previous algorithm POSS  by incorporating the recombination operator, which is a characterizing feature of evolutionary algorithms. A Readme file and example files are included in the package.
