Finding the symmetry group of an LP with equality constraints and its application to classifying orthogonal arrays
Andrew J. Geyer, Dursun A. Bulutoglu, Kenneth J. Ryan
For a given linear program (LP) a permutation of its variables that sends feasible points to feasible points and preserves the objective function value of each of its feasible poin…
