UG
Ubiquity Generator framework
Ubiquity Generator framework
UG is a generic framework to parallelize branch-and-bound based solvers (e.g., MIP, MINLP, ExactIP) in a distributed or shared memory computing environment.
Base solvers and communication libraries are abstracted within UG. A parallel solver instantiated by UG framework is named:
