ReSHOP
Usage
The following statement can be used inside your GAMS program to specify using ReSHOP
Option EMP = ReSHOP;
The above statement should appear before the Solve statement. If ReSHOP was specified as the default solver during GAMS installation, the above statement is not necessary.
Specification of ReSHOP Options
Options can be specified by a ReSHOP options file. A ReSHOP options file consists of one option or comment per line. A pound sign (#) at the beginning of a line causes the entire line to be ignored. Otherwise, the line will be interpreted as an option name and value separated by an equal sign (=) and any amount of white space (blanks or tabs).
