Mixed Complementarity Problem (MCP) is a problem formulation in mathematical programming. Many well-known problem types are special cases of, or may be reduced to MCP. It is a generalization of nonlinear complementarity problem (NCP).

Definition

The mixed complementarity problem is defined by a mapping F ( x ) : R n R n , lower values i R { } and upper values u i R { } .

The solution of the MCP is a vector x R n such that for each index i { 1 , , n } one of the following alternatives holds:

  • x i = i , F i ( x ) 0 ;
  • i < x i < u i , F i ( x ) = 0 ;
  • x i = u i , F i ( x ) 0 .
  • Another definition for MCP is: it is a variational inequality on the parallelepiped [ , u ] .
