Update (September 2026): The article covers new versions of cuOpt 26.08 and HiGHS 1.15.1 which comes with a parallel B&C now utilizing the 24 cores more effectively. Moreover, the result tables of the previous iterations have been added at the end of this page to see the progress over versions and hardware improvements.
Workshop slides introducing mathematical optimization with GAMSPy, from modeling fundamentals and solver selection to data handling and practical Python workflows.
In early 2024, the last steps in the integration of the McCarl GAMS User Guide with the GAMS documentation will be completed. The McCarl Guide will no longer be pointed to or available from the GAMS docs, although it is available on Bruce McCarl’s web site or the GAMSWORLD forum (see links below). While these last steps may go unnoticed by many GAMS users, the integration process has resulted in a much better documentation that all have benefited from. Reaching this milestone provides us a good opportunity to look back at the history of the McCarl Guide. In this article, we consider the original purpose of the Guide, the positive impact it has had during the many years of its use, and the reasons for its retirement.
