The format for each data card type is the standard one discussed in
the RANDQP manuals [4,2]. MPSRAND will not, however, produce an input
deck suitable for the RANDQP even if the Q matrix is symmetric. NPSRAND
assumes that all Q-matrix coefficients are specified explicitly in the
input problem. The output file has all the coefficients in the matrix
section arranged by column. Since the standard QP problem in the
Takayama modeling approach is a maximization problem, and the original
RANDQP assumes minimization problem the Q-matrix and linear OBJ coeffi-
cients are reversed in sign by the MPSRAND program. In the more general
LCP problem, this manipulation is justifiable in terms of the economic
equilibrium conditions for the model. The source listing for MPSRAND is
presented in Figure 12.
































 4LCRAND and RANDQP restrict the number of characters in row and
column names to 6. The QMATGEN allows 7 characters. Therefore, only
QMATGEN type decks that have names with < 6 characters can be success-
fully converted by the MPSRAND program.
