public OpenWboSolver(java.lang.String binaryLocation)
```
    Creates a new solver based on the open-wbo executable given as a parameter.
    
    Parameters:
    
    binaryLocation - the path to the executable.

public Interpretation<PlBeliefSet,PlFormula> getWitness(java.util.Collection<PlFormula> hardConstraints,
                                                              java.util.Map<PlFormula,java.lang.Integer> softConstraints)
```
    Description copied from class: MaxSatSolver
    
    Returns an interpretation with maximal weight on the soft constraints (or null if the hard constraints are not satisfiable)
    
    Specified by:
    
    getWitness in class MaxSatSolver
    
    Parameters:
    
    hardConstraints - a set of propositional formulas
    
    softConstraints - a map mapping clauses to weights (if there is a formula, which is not a clause, i.e. a disjunction of literals), an exception is thrown.
    
    Returns:
    
    an interpretation with maximal weight on the soft constraints (or null if the hard constraints are not satisfiable)
