Write Parameter File

Type

Selection

Range

The settings listed below

Default

No

By setting this option to ‘Yes’ a CPLEX parameter file will be written. The file will be named cpxddddd.prm, where ddddd denotes a 5-digit sequence number. Parameter files are written only if one of the options LP File, MPS or Sav File is set to ‘At the first solve’ (in which case a parameter file is written for the first solve) or ‘At every solve’ (in which case parameter files for every solve are written).

Possible values of this option are:

  • No

  • Yes

A CPLEX parameter (PRM) file is used to specify parameter settings. The file consists of parameter-value pairs, each on its own line. The following is a simple example:

CPLEX Parameter File Version 22.1

CPX_PARAM_PERIND 1

CPX_PARAM_EPPER 3.45000000000000e-06

CPX_PARAM_STARTALG 2

The parameters are printed using the CPLEX C API names as can be found in the:ref:CPLEX_to_AIMMS_Mapping from AIMMS option names to CPLEX parameter names.

Note

  • Only parameters (options) with non-default values according to CPLEX will be printed.
