Mathematical programming with equilibrium constraints (MPEC) is the study of
constrained optimization
In mathematical optimization, constrained optimization (in some contexts called constraint optimization) is the process of optimizing an objective function with respect to some variables in the presence of constraints on those variables. The ob ...
problems where the constraints include
variational inequalities or
complementarities. MPEC is related to the
Stackelberg game.
MPEC is used in the study of
engineering design,
economic equilibrium
In economics, economic equilibrium is a situation in which economic forces such as supply and demand are balanced and in the absence of external influences the ( equilibrium) values of economic variables will not change. For example, in the st ...

multilevel games
Multilevel or multi-level may refer to:
* A hierarchy
A hierarchy (from Greek: , from , 'president of sacred rites') is an arrangement of items (objects, names, values, categories, etc.) that are represented as being "above", "below", or "at th ...
.
MPEC is difficult to deal with because its
feasible region is not necessarily
convex
Convex or convexity may refer to:
Science and technology
* Convex lens, in optics
Mathematics
* Convex set, containing the whole line segment that joins points
** Convex polygon, a polygon which encloses a convex set of points
** Convex polytop ...
or even
connected.
