The solve trace option is invoked via a GAMS solver options file.
Usually, options to specify a filename of the trace file to be created
and options to specify time and node intervals are available.
Please refer to the GAMS solver manuals for the exact names of these options (search for
A sample solve trace file is miptrace.mtr where the file includes statistics of a GAMS run using the MIP model blend2 from the Performance Library and the solver XPRESS.
1. lineNum: GAMS index to be able to read in the file as a table. 2. seriesID: S=start, N=Node, T=time information, E=end. 3. node: 4. seconds: time after solve start. 5. bestFound: best integer solution at a given time or node. 6. bestBound: best bound at a given time or node.
