    v1 v2  
    1 When Sage's MixedIntegerLinearProgram class is used for solving an LP, one frequently needs to access further information about the current basis (often, the optimal basis after solving the LP), not just the numerical values of the solution; in particular, the combinatorial information: which variables are basic, nonbasic at-lower, nonbasic at-upper.
