Fixing Execution Errors

Top  Previous  Next

The execution of a GAMS program passes through a number of stages, one of which is the execution step.  During execution, errors can be detected.  Generally these occur during

 

GAMS execution

Model generation or

Solver execution.

 

Generally, the cause of such problems is

 

Job requirements in excess of GAMS limits

Technical arithmetic problems where an illegal operation is performed

Critical model structure flaws

 

These notes cover the process of finding and fixing GAMS execution errors.
