Simplex method unbounded solution example
WebbThe simplex algorithm (minimization form) can be summarized by the following steps: Step 0. Form a tableau corresponding to a basic feasible solution (BFS). For example, if we assume that the basic variables are (in order) x 1;x 2;:::x m, the simplex tableau takes the initial form shown below: x 1x 2::: x mx m+1x m+2::: x j::: x nRHS 1 0 ::: 0 a WebbYou need to explain that the solution is not unbounded in a minimization problem as it is in a maximization problem. ...
