Comment(by malb):
The patch looks good, I'm running long doctests on sage.math now. Can I
assume you ran doctests for CPLEX and Coin (i.e. with the optional
packages installed)? I think the only remaining issue is:
{{{
#!python
sage: p = MixedIntegerLinearProgram()
sage: p.new_variable(name="foo")
MIPVariable of dimension 1.
sage: x = _
sage: p.add_constraint(0 <= x[1] <= 2)
sage: p.show()
Maximization:
Constraints:
x_0 <= 2.0
Variables:
x_0 is a real variable (min=0.0, max=+oo)
}}}
For some reason MIPVariable ignores the optional name parameter and
hardcodes "x". Is there a reason for this?
