راه حل های چندگانه در مسئله برنامه نویسی خطی

By applying the Simplex Algorithm, Matlab, or WolframAlpha one of these two answers is obtained: there is (a) solution or there is no solution. We continue the investigation started in [1], where two more subcases were attached when the solution exists. We give also several examples, in which we are able to further specify the standard answers given by Simplex Algorithm or/and by the computer algebra systems implemented for the linear programming problems. The problems are solved here by our extended algorithm. In the case of multiple solutions, we are able to select the closest one to a previously given point. A model of an electric power system is used to exemplify this goal.
