coin-or-Alps

CHiPPS is the COIN-OR High-Performance Parallel Search Framework, a framework for implementing parallel algorithms based on tree search. The current CHiPPS architecture consists of three layers. The Abstract Library for Parallel Search (ALPS) is the base layer of a hierarchy consisting of implementations of various tree search algorithms for specific problem types. The Branch, Constrain, and Price Software (BiCePS) is a data management layer built on top of ALPS for implementing relaxation-based branch and bound algorithms. The BiCePS Linear Integer Solver (BLIS) is a concretization of the BiCePS layer for solving mixed-integer linear programs. ALPS, BiCePS, and BLIS are sub-repositories of the CHiPPS Subversion repository.
