Use of solver with inequalities

[tge20]

Hi Benjamin,

I'm using your code for my bachelor thesis to get first results for the combination of treewidth and n-fold programming. All my n-fold formulations have inequalities in their matrices (<=) which is not supported by your program. I changed the code in some places to enable that behavior and to pass to the Gurobi model 'GRB_EQUAL', 'GRB_LESS_EQUAL', etc. in dependence of the current equation type. Unfortunately the program does not work anymore and it won't find solutions / correct solutions for my instances. I'm wondering whether it is in general possible to include inequalities some way and it would be fantastic if you have an idea.

Thanks in advance,
Tim
