Description (last modified by )
Here's a bug:
sage: p.<x,y> = MixedIntegerLinearProgram() sage: x[0], y[0] (x_0, x_1) sage: p.set_max(x, 42) sage: p.get_max(y[0]) 42.0
The bug is in MIPVariable.set_min
, .set_max
, which calls back into the problem to change the bounds of *all* variables of the problem rather than just its components.
