Solve LP by Excel solver Example 1: min Z=3x1 2x2 s.t 2x1+x2 ≥ 10 -3x1+2x2 ≤6 C1+C2 ≥6 x1≥0， x2≥0. ● This problem is called linear programming problem,since the objective function and the constraints are linear and the decision variables are continuous. If all the decision variable can only take integer value,then the problem is called the integer programming problem. If some of the decision variables take only the integer value,this problem is called the mixed-integer programming problemSolve LP by Excel solver Example 1:  This problem is called linear programming problem, since the objective function and the constraints are linear and the decision variables are continuous.  If all the decision variable can only take integer value, then the problem is called the integer programming problem.  If some of the decision variables take only the integer value, this problem is called the mixed-integer programming problem
