Description
CVXOPTBackend forgets to set its initial problem_name, and as a result the MixedIntegerLinearProgram
cannot print itself.
sage: p = MixedIntegerLinearProgram(solver="CVXOPT") sage: p  TypeError Traceback (most recent call last) ... TypeError: cannot concatenate 'str' and 'NoneType' objects <repr(<sage.numerical.mip.MixedIntegerLinearProgram at 0x190970a70>) failed: TypeError: cannot concatenate 'str' and 'NoneType' objects>
