Description
This model compares the solvers and their capabilities on the actual system with the original solver capability database. It then runs all combinations with solvers known to the global database and checks if the return code of a GAMS run is 0. All exceptions are captured in a compare report. If the report is not empty, the model will terminate with an execution error. Keywords: GAMS language features

$title Compare the actual System with the original Solver Database (GSOLVER,SEQ=311)
$onText
This model compares the solvers and their capabilities on the
actual system with the original solver capability database.
It then runs all combinations with solvers known to the global database
and checks if the return code of a GAMS run is 0.
All exceptions are captured in a compare report. If the report is not empty,
the model will terminate with an execution error.
