Vol (Volume Algorithm)
Vol (Volume Algorithm) is an open-source implementation of a subgradient method that produces primal as well as dual solutions. The primal solution comes from estimating the volumes below the faces of the dual problem. This is an approximate method so the primal vector might have small infeasiblities that are negligible in many practical settings. The original subgradient algorithm produces only dual solutions.
