ABSTRACT


 This manual provides basic instruction in the use of the LCRAND
mathematical programming software. LCRAND, a modified version of
RANDQP, provides an efficient methodology for solving linear comple-
mentarity programming problems arising from economic models involving
international trade and other problems requiring optimization of a
non-linear objective function subject to a set of linear constraints.
LCRAND is unique in that it can handle problems in which the inter-
action terms between activities are not symmetric--a limitation of
quadratic programming solution algorithms. Experience to date indicates
LCRAND is efficient and reliable in solving small and intermediate
size problems.



 Key words: Linear programming, Quadratic programming, Linear
complementarity programming.
