Test routine 1, calls CPLEX Matlab level 1 interface to solve a GAP problem.

Calling Syntax

x = cpxTest1

Global Parameters Used

Parameter Description
MAX_x Maximal number of x elements printed in output statements. Default 20.
MAX_c Maximal number of constraint elements printed in output statements. Default 20.


Running a generalized assignment problem (GAP) from Wolsey. In this test the linear sos1 constraints are defined explicitly.

Given the matrices A (constraints) and C (costs), cxpTest1 is using the utility abc2gap to reformulate the problem into the standard form suitable for CPLEX.

The number of iterations are increased, no presolve is used, and an aggressive cut strategy.
