### README for the Open-WBO MaxSAT Solver
### Version 1.3.0 -- 1 January 2015

Open-WBO is an extensible and modular open-source MaxSAT Solver.
Open-WBO was the best non-portfolio solver in the unweighted and partial 
industrial categories at the MaxSAT Evaluation 2014.

Usage of the solver:
./open-wbo [options] <input-file>

The following options are available in Open-WBO:

### Global Options
#
# Verbosity level (0=minimal, 1=more)
-verbosity    = <int32>  [   0 ..    1] (default: 1)

# Limit on memory usage in megabytes
-mem-lim      = <int32>  [   0 .. imax] (default: 2147483647)

# Limit on CPU time allowed in seconds
-cpu-lim      = <int32>  [   0 .. imax] (default: 2147483647)

# Search algorithm (0=wbo, 1=linear-su, 2=linear-us, 3=msu3, 4=wmsu3, 5=best)
-algorithm    = <int32>  [   0 ..    1] (default: 5)

# BMO search 
-bmo,-no-bmo (default on)

# Incremental strategy (0=none, 1=blocking, 2=weakening, 3=iterative)
-incremental  = <int32>  [   0 ..    3] (default: 3)

# Pseudo-Boolean encodings (0=SWC)
-pb           = <int32>  [   0 ..    0] (default: 0)

# At-most-one encodings (0=ladder)
-amo          = <int32>  [   0 ..    0] (default: 0)

# Cardinality encodings (0=cardinality networks, 1=totalizer, 2=modulo totalizer)
-cardinality  = <int32>  [   0 ..    2] (default: 1)

       
### WBO Options (algorithm=0, unsatisfiability-based algorithm)
#
# Weight strategy (0=none, 1=weight-based, 2=diversity-based)
-weight-strategy = <int32>  [   0 ..    2] (default: 2)

# Symmetry breaking
-symmetry, -no-symmetry (default on)

# Limit on the number of symmetry breaking clauses
-symmetry-limit = <int32>  [   0 .. imax] (default: 500000)
