Solver Option Files

Most of the GAMS solvers allow users to affect aspects of their operation by specifying an options file.  In general, users do not need to exercise such options, as the default settings are usually appropriate for most problems.  However, in some cases, it is possible to improve solver performance by specifying non-standard values.  This chapter shows how to use option files.
