CPLEX 11 191
1 Generate MIR cuts moderately
2 Generate MIR cuts aggressively
mpslongnum (integer)
Determines the precision of numeric output in the MPS and REW file formats. When this parameter is set
to its default value 1 (one), numbers are written to MPS files in full-precision; that is, up to 15 significant
digits may be written. The setting 0 (zero) writes files that correspond to the standard MPS format, where
at most 12 characters can be used to represent a value. This limit may result in loss of precision.
(default = 1)
0 Use limited MPS precision
1 Use full-precision
names (integer)
This option causes GAMS names for the variables and equations to be loaded into Cplex. These names will
then be used for error messages, log entries, and so forth. Setting names to no may help if memory is very
tight.
(default = 1)
netdisplay (integer)
This option controls the log for network iterations.
(default = 2)
0 No network log.
1 Displays true objective values
2 Displays penalized objective values
netepopt (real)
This optimality tolerance influences the reduced-cost tolerance for optimality when using the network simplex
method. This option setting governs how closely Cplex must approach the theoretically optimal
solution.
Range: [1e-011,0.1]
(default = 1e-006)
neteprhs (real)
This feasibility tolerance determines the degree to which the network simplex algorithm will allow a flow
value to violate its bounds.
Range: [1e-011,0.1]
(default = 1e-006)
netfind (integer)
Specifies the level of network extraction to be done.
(default = 2)
1 Extract pure network only
2 Try reflection scaling
3 Try general scaling
netitlim (integer)
Iteration limit for the network simplex method.
(default = large)
