HiGHS has the world’s best open-source MIP solver – it’s far superior to CBC, which is the only open-source MIP solver that you support – and today we received a request for “Support / Integration for AIMMS modelling”
https://github.com/ERGO-Code/HiGHS/issues/3374
HiGHS is distributed and supported as a solver in AMPL and GAMS, and I was wondering when it might appear in AIMMS. Perhaps now is the time! We're prepared to do some work our end but, given the number of commercial companies that have incorporated HiGHS, I don't expect the task to be painful for either party.
Thanks,
Julian Hall
