Appendix 3 Differentiable ILP Loss 3.2 A Solver-free Framework

Figure on the left shows 4 ground truth constraints that need to be learnt. Blue dots are the only feasible integral points w.r.t. the 4 constraints. Shaded area containing only the dot with green border is the feasible region after we add the cost constraint (dashed line). Figure on the right shows an intermediate scenario while learning. Figure 1a shows the ground truth ILP.
