This file: \* MtxLP *\ Maximize OBJ: C + A + B + D Subject To _C1: - A - B = 0 _C2: - A + C - D = 0 Bounds A <= 1 B <= 1 D <= 1 C <= 1 End
causes glpsolto bomb out with the message: lpx_read_cpxlp: reading problem data from `MtxLP-pulp.lp'... MtxLP-pulp.lp:9: symbol `B' in wrong position CPLEX LP file processing error It can be fixed by simply renaming variables: \* MtxLP *\ Maximize OBJ: See + Aye + Dee + Bee Subject To _C1: - Aye - Bee = 0 _C2: - Aye + See - Dee = 0 Bounds Dee <= 1 Aye <= 1 See <= 1 Bee <= 1 End But I can find nothing that suggests that that single letter variables, other than possibly E|e can cause problems. Can anyone explain this and point me to a definitive description of cplex syntax ?
