 <p>This code snippet creates an infeasible model with two constraints and finds the IIS of the model. Obviously, the constraints are contradictory because <code class="docutils literal notranslate"><span class="pre">x</span> <span class="pre">+</span> <span class="pre">2</span> <span class="pre">*</span> <span class="pre">y</span> <span class="pre">&lt;=</span> <span class="pre">1</span></code> and <code class="docutils literal notranslate"><span class="pre">x</span> <span class="pre">+</span> <span class="pre">y</span> <span class="pre">&gt;=</span> <span class="pre">5</span></code> cannot be satisfied at the same time when <code class="docutils literal notranslate"><span class="pre">x</span></code> and <code class="docutils literal notranslate"><span class="pre">y</span></code> are non-negative. The optimizer will detect that the model is infeasible and return the IIS, which is the set of constraints that cause the infeasibility. We can query whether a constraint is in the IIS by calling <code class="docutils literal notranslate"><span class="pre">get_constraint_attribute</span></code> with the <code class="docutils literal notranslate"><span class="pre">ConstraintAttribute.IIS</span></code> attribute.</p>
