CPLEX 11 205
workdir (string)
The name of an existing directory into which Cplex may store temporary working files. Used for MIP node
files and by out-of-core Barrier.
(default = current or project directory)
workmem (real)
Upper limit on the amount of memory, in megabytes, that Cplex is permitted to use for working files. See
parameter workdir.
(default = 128)
writebas (string)
Write a basis file.
writeflt (string)
Write the diversity filter to a Cplex FLT file.
writelp (string)
Write a file in Cplex LP format.
writemps (string)
Write an MPS problem file.
writeord (string)
Write a Cplex ord (containing priority and branch direction information) file.
writepre (string)
Write a Cplex LP, MPS, or SAV file of the presolved problem. The file extension determines the problem
format. For example, writepre presolved.lp creates a file presolved.lp in Cplex LP format.
writesav (string)
Write a binary problem file.
zerohalfcuts (integer)
Decides whether or not to generate zero-half cuts for the problem. The value 0, the default, specifies that
the attempt to generate zero-half cuts should continue only if it seems to be helping. If the dual bound of
your model does not make sufficient progress, consider setting this parameter to 2 to generate zero-half cuts
more aggressively.
(default = 0)
-1 Off
0 Automatic
1 Generate zero-half cuts moderately
2 Generate zero-half cuts aggressively
