This category contains optimization problems with complementarity constraints (MPCCs), for generic variables / functions y_1, y_2, y_3 in the form of


\begin{array}{llcl}
 \displaystyle \min_{y_1, y_2, y_3} & & & \Phi(y_1, y_2, y_3)   \\[1.5ex]
 \mbox{s.t.} & 0 & = & F ( y_1, y_2, y_3), \\
 & 0 & \le & C ( y_1, y_2, y_3),  \\
 & 0 & \le & y_1 \perp y_2 \ge 0,
\end{array}

The complementarity operator \perp implies the disjunctive behavior


y_{1,i} = 0 \quad{\mbox{ OR } }\quad y_{2,i} = 0 \quad \quad \forall \; i = 1 \dots n_y.

MPCCs may arise from a reformulation of a bilevel optimization problem by writing the optimality conditions of the inner problem as variational constraints of the outer optimization problem, or from a special treatment of state-dependent switches, <bibref>Baumrucker2009</bibref>. Note that all MPCCs can be reformulated as MPECs.
