Comment (by ncohen):
Yep, but then we would have two ways to do the same thing, with methods
that take different arguments. What about changing get_min and get_max so
that they accept integers instead ?
All that would need to be added is a type check : if the given value is a
MIPVariable type then the old code (one line) is used, and otherwise the
backend function is called.
Actually, the only line that this function contains is
{{{
return self._backend.variable_lower_bound(self._variables[v])
}}}
That is : first take the integer corresponding to the variable, then
return the value. More or less what you want to do too `:-P`
