Here is the video about linear programming problem lpp using two phase simplex method in operations research, in this video we discussed briefly and solved one illustration problem on. Comparison of bigm method and two phase methods in. In phase i, we form a new objective function by assigning zero to every original variable including slack and surplus variables and 1 to each of the artificial. The bigm method of handling instances with artificial variables is the commonsense approach. Big m method an alternative to the two phase method of finding an initial basic feasible solution by minimizing the sum of the artificial variables, is to solve a single linear program in which the objective function is augmented by a penalty term. These videos are useful for examinations like nta ugc net computer science and applications, gate computer science, isro, drdo. Authors proposed both, a mathematical model and a two phase insertion algorithm, in which a feasible solution is first generated and later improved.
