1. Linear Programming, the Simplex Algorithm and Simple Polytopes

Das Sashi Bhusan; Biswal Bagaban; J.P Tripathy

Volume 6, Issue 1 , Winter 2014, , Pages 702-719

Abstract
  In the first part of the paper we survey some far reaching applications of the basis facts of linear programming to the combinatorial theory of simple polytopes. In the second part we discuss some recent developments concurring the simplex algorithm. We describe sub-exponential randomized pivot roles ...  Read More

2. Some Results on facets for linear inequality in 0-1 variables

D. Sashi Bhusan; B. Bagaban; J.P. Tripathy

Volume 4, Issue 1 , Winter 2012, , Pages 292-303

Abstract
  The facet of Knapsack ploytope, i.e. convex hull of 0-1 points satisfying a given linear inequality has been presented in this current paper. Such type of facets plays an important role in set covering set partitioning, matroidal-intersection vertex- packing, generalized assignment and ...  Read More
