Output File

Type : Selection

Range : The settings listed below

Default : No

This option can be used to activate the generation of a COPT output file. The output file is named “copt.log” and is placed in the log-directory of the current project. Possible values are:

• No

• Yes

Remark

The logging information is written to the output file only if the general solvers option Solver Listing Messages is set to ‘All’ or ‘Remark’. To copy the logging information to the listing file the general solvers option Solver Listing should be set to a value different than ‘Never’.

There is no difference between settings ‘All’ and ‘Remark’ for option Solver Listing Messages , except that with setting ‘All’ also information is logged for LP problems solved while calculating shadow price ranges for constraints or value ranges for variables; see the option Sensitivity Method .
