GAMS World Forum

Hi

Since Version 24.8.1 the summary now also gives as information: "Projected". The release notes tell me
"the number of variables and equations where the level was projected to one of the bounds (compare model attribute tolProj), if that number is greater than 0."
Could any explain what this means in lay terms...? Or just give a reference with some more explanation?

Thanks

Renger,

This is about the solution reading of GAMS. If the solver return a level of a variable, which is close to one of its bound (where "close to" can be controlled by the mentioned model attribute tolProj, the default is 1e-8), GAMS "projects" this value to the bound, so reports the bound value instead of the value returned by the solver. And the "PROJECTED" entry reports the number of variables which were treated this way.

I hope that helps!
Best,
Lutz
