Ace CSP Solver

by Eugen Sawin esawin@me73.com

Version

This is the version that was used to win the competition at the CSPs course at the University of Freiburg.
It is a stripped version of the original solver missing a lot of (suboptimal/not optimized) techniques and supporting only binary constraints.
At some point, I will merge the original features back into this repository, as long as they provide good results and don't break the efficiency of the general approach.

Requirements

  • POSIX.1b-compliant operating system (librt)
  • GNU GCC 4.6 or newer
  • GNU Make
  • Python 2.7 or newer (only for style checking)

Dependencies

Required

Optional

Building gflags

The repository contains a slightly modified gflags version with less verbose help output.
If you want to use the provided version instead, you need to build gflags locally:

$ make gflags

and then activate the two lines in the makefile, which are commented out. Alternatively you can build all dependencies at once:

$ make depend

Building Ace (depends on gflags)

To build Ace use:

$ make

For performance measuring use the more optimised version:

$ make opt

Using Ace

To start ace use:

$ ace xcsp-input.xml

To show the full usage and flags help use:

$ ace -help

Running Ace performance tests

To run performance tests on some benchmark problems use:

$ make perftest

All test parameters can be changed on invocation like this:

$ make perftest ARGS="-consistency=ac2001 -verbose"

Testing Ace (depends on gtest)

To build and run the unit tests use:

$ make check

Profiling Ace (depends on gperftools)

To build Ace with profiling turned on use:

$ make profile

Getting cpplint

Code style checking depends on a modified version of Google's cpplint. Get it via

$ make cpplint

Checking style (depends on cpplint)

To test code style conformance with the Google C++ Style Guide use:

$ make checkstyle
