Reformulations of mathematical programming problems as linear complementarity problems [PDF]

open access: yes, 1982
A family of complementarity problems are defined as extensions of the well known Linear Complementarity Problem (LCP). These are (i.) Second Linear Complementarity Problem (SLCP) which is an LCP extended by introducing further equality restrictions and ...
