The source files of Open-WBO are the following:

Makefile - Compiles the source files

clean.sh - Script for easy cleaning of compiled files

compile.sh - Script for easy compilation with different SAT solvers

Main.cc - Main options for Open-WBO

Dimacs.h - MaxSAT parser

Soft.h - Soft clauses class

Hard.h - Hard clauses class

MaxTypes.h - Useful enumerators

Encoder.* - Interface for the different encodings

MaxSAT.* - Parent class for the different MaxSAT algorithms

algorithms/ - Subdirectory with MaxSAT algorithms

algorithms/Alg_* - Source files for MaxSAT algorithms

encodings/ - Subdirectory with MaxSAT encodings

encodings/Encodings.* - Parent class for the different encodings

encodings/Enc_* - Source files for encodings of linear constraints to CNF

solvers/ - Subdirectory with SAT solvers

solvers/X/ - Source files of SAT solver X

Open-WBO is compiled like MiniSAT. The option "s" statically compiles Open-WBO, and the option "r" compiles Open-WBO in release mode. For example:

make rs - compiles Open-WBO statically ("s") in release mode ("r")

make - compiles Open-WBO dynamically in debug mode

Any MiniSAT-like SAT solver may be used with Open-WBO. If you want to use a new SAT solver (e.g. "MiniSAT 2.0"), it is necessary to crease a subdirectory (e.g. "minisat2.0") inside the "solvers" directory and change the Makefile accordingly:

# VERSION = core or simp

# SATSOLVER = name of the SAT solver

# SOLVERDIR = subdirectory of the SAT solver

# NSPACE = namespace of the SAT solver

#

# e.g. MiniSAT 2.0 compilation with simp version:

#

VERSION = simp

SATSOLVER = "MiniSAT 2.0"

SOLVERDIR = minisat2.0

NSPACE = Minisat

# THE REMAINING OF THE MAKEFILE SHOULD BE LEFT UNCHANGED

The following SAT solvers are included in this version of Open-WBO: (i) minisat2.0, (ii) minisat2.2, (iii) glucose2.3, (iv) glucose3.0, (v) zenn, (vi) sinn, (vii) glueminisat, (viii) gluh, (ix) glue_bit, (x) glucored. We would like to thank the authors of those solvers for making their source code publicly available. Further information regarding those solvers may be found in the following references.
