Detailed Description

status of variables.

Author:

After the solution of a linear program by the simplex method each variable receives a status indicating if the variable is contained in the basis of the optimal solution, or is nonbasic and has a value equal to its lower or upper bound, or is a free variable not contained in the basis. We extend this notion since later in the interface from a cutting plane algorithm to the linear program variables might be eliminated.
