- More than 32.000 identifiers supported
- Re-introduction of expiration date on encrypted models
- Addition of Gurobi 6.0 solver
Some of our customers have found the limit in AIMMS of roughly 32.000 identifiers unsuitable for their largest models and their models that use runtime libraries heavily. Therefore, we have adapted AIMMS to support models which contain far more than 32.000 identifiers.
As a result of customer feedback, we have re-introduced the concept of setting an expiration date on encrypted AIMMS models. This means that you can time-limit the use of the encrypted .aimmspack files that you distribute. You can also set the number of days (anywhere between 0 and 99) before the actual expiration date, from which moment on the users of your .aimmspack files will get a warning message about the upcoming expiration of their model.
In this AIMMS release, a new version of Gurobi was added: Gurobi 6.0. This version offers performance improvements over earlier Gurobi versions.
Detailed information about all new features in AIMMS 4.2 can be found here and in its release notes. AIMMS 4.2 is available to everyone who is trying out AIMMS, to everyone with an AIMMS license that is in maintenance, and to everyone buying a new AIMMS license. If you do not have a maintained license, you can request a trial license or apply for maintenance on an existing license at firstname.lastname@example.org. More news…
