Distinguish between Basic feasible solution and Optimal solution in LPP. (Apr 2005)
Basic feasible solution means the 1st simplex table. In basic feasible solution, the basic variables are slack variables. The Z value, i. e. profit value of that table is zero.
Optimal solution means the last table of simplex. In this table, all “C – Z (delta)” values, i. e. opportunity costs are either zero or negative. Hence, no further improvement in the solution is possible. The profit of this table is maximum. No further increase in profit is possible.
