Minimize the Generation Cost Function by Two-Phased Simplex Method by Code or Linpro Command.

Minimize the Cost Function, Z = A1PG1+A2PG2+A3PG3.
Constraints are;
PG1+PG2+PG3 = PD4. PG1+PG2 <= PL.
PG1 <= PG1max. PG2 <= PG2max. PG3 <= PG3max.
PG1, PG2, PG3 >= 0.

Where,
PG = Plant Generation
PL = Transmission Line Load Capacity
PD = Demand
A = Cost Constants of Generating Electricity

* If we have profit constants, instead of cost constants, then we would like to maximize the function Z, instead of minimizing it. That's why the program also has an option to select between minimize or maximize function.
