    int
    getBound()
    Returns the current bound
    void
    relax()
    Relax the objective it can be deteriorated
    void
    setBound(int newBound)
    Sets the new value of the bound
    void
    setDelta(int delta)
    Sets the new value of the bound as the one of the current solution + (maximization) or - (minimization) delta
    void
    setFilter(boolean activate)
    Activates or deactivates the filtering of the objective
    void
    tighten()
    Method called each time a solution is found during the search to let the tightening of the primal bound occurs such that the next found solution is better.
