** check different types of Two-Phase method examples
Algorithm and examples
1. If you want simplex solution in your study format, then mail me one simplex problem with detailed solution steps. If possible, I will try my best to develop it.
2. To solve a bug, code is changed (on 30-Oct-18), So it may be possible previously working problem may give error (1% chances).
Method
1. Simplex (BigM) method
2. TwoPhase method
3. Dual simplex method
4. Integer simplex method
5. Graphical method
6. Primal to Dual
7. Branch and Bound method
8. 0-1 Integer programming problem
