For when you need to branch and bound in parallel.
For parallel execution, start Julia with the -t flag.
Given functions
bound :: Node -> lower_bound, feasible_value, feasible_arg,branch :: Node -> Node[],
a root Node, and a gap, PBaB will branch and bound in parallel using a best-first strategy. PBaB stops when it finds a feasible solution with a value within gap of the global minimum.
This package is in very early stages of development. Feel free to open issues. Any help is appreciated.
