Simplex methodBig M methodParameter evaluationIn the simplex method of linear programming, there is a big M method (the penalty factor method)forfinding an initial feasible basis.The current textbooks of operationsresearch only explain that the big M method isefficient when M is large enough, and...
The simplex method is a systematic approach to traverse the vertices of the polyhedron containing feasible solutions in a linear programming problem. It aims to find the optimal solution by iteratively improving the objective function value. This method is considered one of the greatest inventions of...
In this paper we study linear-programming based approaches to the maximum matching problem in the semi-streaming model. In this model edges are presented sequentially, possibly in an adversarial order, and we are only allowed to use a small space. The allowed space is near linear in the numbe...

The general idea behind the randomized rounding method is: (1) An NP-hard problem is first transformed into a 0–1 Integer Programming (IP) problem. (2) Then, it is relaxed to a Linear Programming (LP) problem. (3) For the optimal solution to LP, the value of each variable is ...

Our algorithm uses the solution of the linear relaxation of a time-indexed Mixed-Integer formulation of the problem. In addition, a heuristic method inspired by this approximation algorithm is presented and is numerically shown to out-perform known methods for a large set of standard test problems...
