Type of Solutions : Basic, Feasible/Infeasible, Optimal/ Non-Optimal,

• Analysis of Solution
1. This is a Basic solution, as values of basic variables are Positive
2. This is a feasible solution, as values of basic variables, not containing
Artificial Variable, are Positive and all constraints are satisfied
3. This Feasible solution is an Optimal, as all values in Index Row are positive.
4. If there is an Artificial Variable, as Basic variable in final table, it is called as
Infeasible solution
5. This solution is unique Optimal, as the number of zeroes are equal to number
of basic variables in Index Row in final Table.
6. If the number of zeroes are more than number of basic variables in Index Row
in final Table, it is a case of more than one optimal solutions.
7. This is a Bounded Solution, as the values of all Basic variables in final table,
are finite positive.
8. This is a Non-degenerate Solution, as value of none of the basic variables is
Zero , in final table.
9. If value of at least one of the basic variables is Zero in Index Row in final
Table, it is a Degenerate Solution.

2 x1 - x2 - x3 ? 2
2x1 - 2x2 - 3x3 ? 6

s/t y1 + 2 y2 + 2y3 ? 1
y1 - y2 - 2y3 ? -1
