Projects such as this one are maintained by a small group of volunteers under the auspices of the non-profit COIN-OR Foundation and we need your help! Please consider sponsoring our activities or volunteering to help!

Welcome to BiCePS, (Branch, Constrain, and Price Software), a data-handling layer of the CHiPPS (COIN-OR HIgh Performance Parallel Search) framework. CHiPPS is a framework for implementing parallel graph search algorithms. Its methodology generalizes many of the notions of an LP-based branch-and-bound algorithm, allowing the implementation of a wide range of algorithms with a simplified interface. BiCePS implements the data-handling methods required for implementing relaxation-based branch-and-bound. It is an intermediate layer of the CHiPPS library hierarchy that that includes a library for solving mixed integer linear programs (BLIS).

BiCePS is written in C++ and is released as open source under the Eclipse Public License 2.0.

It is distributed under the auspices of the COIN-OR Foundation

The BiCePS development site is https://github.com/coin-or/CHiPPS-BiCePS.

Paper: http://dx.doi.org/10.1023/B:SUPE.0000020179.55383.ad

There is a Docker image that provides BiCePS, as well as other projects in the COIN-OR Optimization Suite here

For newer releases, binaries will be made available as assets attached to releases in Github here. Older binaries are archived as part of CHiPPS-BLIS here.

Due to license incompatibilities, pre-compiled binaries may lack some functionality. If binaries are not available for your platform for the latest version and you would like to request them to be built and posted, feel free to let us know in the discussion formum.

Source code can be obtained either by

• Downloading a snapshot of the source code for the latest release version of BiCePS from the releases page.
• Cloning this repository from Github or
• Using the coinbrew script to get the project and all dependencies (recommended, see below).

Below is a quick start guide for building on common platforms. More detailed build instructions are here.

BiCePS has a number of dependencies, which are detailed in config.yml. Dependencies on other COIN-OR projects are automatically downloaded when obtaining the source with coinbrew. For some of the remaining third-party dependencies, automatic download scripts and build wrappers are provided (and will also be automatically run for required and recommended dependencies), while other libraries that are aeasy to obtain must be installed using an appropriate package manager (or may come with your OS by default).

The quick start assumes you are in a bash shell.

To download and build BiCePS from source, execute the following on the command line.

wget https://raw.githubusercontent.com/coin-or/coinbrew/master/coinbrew
chmod u+x coinbrew
./coinbrew fetch Bcps@master
./coinbrew build Bcps

For more detailed instructions on coinbrew, see https://coin-or.github.io/coinbrew. The coinbrew script will fetch the additional projects specified in the Dependencies section of config.yml.

• Download the source code, e.g., by cloning the git repo https://github.com/coin-or/CHiPPS-BiCePS
• Download and install the source code for the dependencies listed in config.yml
• Build the code as follows (make sure to set PKG_CONFIG_PTH to install directory for dependencies).

./configure -C
make
make test
make install

For configuration and compilation of the parallel version, the user has to specify the location of MPI with options --with-mpi-cflags, --with-mpi-lflags, MPICC, and MPICXX.

./coinbrew build Bcps --enable-static --disable-shared --with-mpi-cflags="$\(pkg-config --cflags mpi\)" --with-mpi-lflags="$\(pkg-config --libs mpi\)" MPICC=mpicc MPICXX=mpiCC

To build the example codes (which is an old version of Blis, just used for testing), configure and build as above. Switch into the appropriate subdirectory in the source distribution and type make.

If you have Doxygen available, you can build a HTML documentation by typing

make doxygen-docs

in the build directory. If BiCePS was built via coinbrew, then the build directory will be ./build/CHiPPS-BiCePS/master by default. The doxygen documentation main file is found at <build-dir>/doxydoc/html/index.html.

If you don't have doxygen installed locally, you can use also find the documentation here.

1. Configurations - Serial: Well tested. - LAMMPI: Well tested. - MPICH: Well tested.

2. Applications (See INSTALL) - Blis: an older version of the Blis solver: Well tested.
