Description (last modified by )
sage: p = MixedIntegerLinearProgram(solver="glpk") sage: bar = p.new_variable(name="bar") sage: bar MIPVariable of dimension 1 sage: bar[0] x_0 sage: bar MIPVariable of dimension 1 sage: bar[1] x_1 sage: bar MIPVariable of dimension 1 sage: p.solve() 0.0 sage: bar.values() [x_0, x_1] sage: p.get_values(bar) {0: 0.0, 1: 0.0}
I think the print method should instead of "dimension 1" (which apparently means tensor order 1, rather than dimension 1 -- see #17643) print some useful information, such as the name of the variable and the dimension (number of components).
