Simplex primal algorithm
Data: acceptable table Result: an optimal or not limited table
1) Choice of a entering column (variable)
To choose a except base column R with a negative reduced cost
If there is not entering column: STOP ! the table running is optimal.
2) Choice of a outgoing column (variable)
To choose a line J minimizing the characteristic quotients
If there is not outgoing column: STOP ! the table running is not limited.
