What is a linear programming problem with no solution?
- A Linear Programming Problem with no solution. The feasible region of the linear programming problem is empty; that is, there are no values for x 1and x 2that can simultaneously satisfy all the constraints.
What is a problem with no solution?
- Problems with No Solution Recall for any mathematical programming problem, the feasible set or region is simply a subset of Rn. If this region is empty, then there is no solution to the mathematical programming problem and the problem is said to be over constrained.
How to convert LP problem into a system of linear equations?
- The simplex method denes an ecient algorithm of ndingthis specic solution of the system of linear equations. Therefore, we need to start with converting given LP problem into asystem of linear equations. First, we convert problem constraints intoequations with the help of slack variables.
Does a linear programming problem with an unbounded set have an optimal solution?
- A linear programming problem with an unbounded set may or may not have an optimal solution, but if there is an optimal solution, it occurs at a corner point. bounded set is a set that has a boundary around the feasible set. A linear programming problem with a bounded set always has an optimal solution.
