Hi all, In the OpenOpt software (BSD-licensed, http://openopt.org ) we have implemented new class - STAB - searching for maximum stable set of a graph. networkx graphs are used as input arguments. Unlike networkx maximum_independent_set() we focus on searching for exact solution (this is NP-Hard problem). interalg or OpenOpt MILP solvers are used, some GUI features and stop criterion (e.g. maxTime, maxCPUTime, fEnough) can be used. Optional arguments are includedNodes and excludedNodes - nodes that have to be present/absent in solution. See http://openopt.org/STAB for details. Future plans (probably very long-term although) include TSP and some other graph problems. ------------------------- Regards, Dmitrey.
