WebbIf we solve this linear program by the simplex method, the resulting optimal solution is y1 =11, y2 =1 2, and v =294. These are exactly the desired values of the shadow prices, and the value of v reﬂects that the ﬁrm’s contribution is fully allocated to its resources. Essentially, the linear program (2), in terms of the WebbThe solution is the two-phase simplex method. In this method, we: 1.Solve an auxiliary problem, which has a built-in starting point, to determine if the original linear program is feasible. If we succeed, we nd a basic feasible solution to the orignal LP. 2.From that basic feasible solution, solve the linear program the way we’ve done it before.

"WebbThe simplex method starts at the origin and shifts from point to point, one coordinate at a time; the “basis” is simply the coordinates of the current point. Changing the basis (pivoting) moves the point along an edge of the simplex to the most promising adjacent point. The process repeats until a maximum is reached. " - Simplex method explained
