Description
Emphasizes precision in numerically unstable or difficult problems. This parameter lets you specify to CPLEX that it should emphasize precision in numerically difficult or unstable problems, with consequent performance trade-offs in time and memory.
Value | bool | Symbol | Interactive | Meaning |
---|---|---|---|---|
0 | false | CPX_OFF | no | Do not emphasize numerical precision; default |
1 | true | CPX_ON | yes | Exercise extreme caution in computation |
