Semi-infinite programming

In mathematics, semi-infinite programming (SIP) is an optimization problem with a finite number of variables and an infinite number of constraints, or a infinite number of variables and a finite number of constraints. In the former case the constraints are typically parameterized by parameters.

Mathematical formulation of the problem

The problem can be stated simply as:

$\min \limits _{x\in X}\;\;f(x)$

${\mbox{subject to: }}\$

$g(x,y)\leq 0,\;\;\forall y\in Y$

where

$f:R^{n}\to R$

$g:R^{n}\times R^{m}\to R$

$X\subseteq R^{n}$

$Y\subseteq R^{m}.$

SIP can be seen as a special case of bilevel programs (Multilevel programming) in which the lower-level variables do not participate in the objective function.
