    Modifier and Type
    Method
    Description
    void
    chemotaxis(Configurator bacterium, Problem problem, Function function)
    In the chemotaxis method the chemotaxis process of TS-MBFOA is performed, where two swims are interleaved, in each cycle one exploitation or exploration swim is performed.
    void
    eliminationDispersal(Configurator bacterium, Problem problem, Function function)
    In the eliminationDispersal method, the worst bacterium is eliminated from the population based on feasibility rules and a new one is randomly generated.
    protected int
    getCount()
    Method that returns the value count.
    int
    getGeneration()
    This method returns the generational number.
    protected boolean
    getInstruction(Configurator configurator)
    Return to TS-MBFOA stop condition.
    void
    grouping()
    The grouping method is a TS-MBFOA process, which is applied in the middle cycle of the chemotaxic process.
    protected void
    increaseCount(int value)
    This method increments an auxiliary counter for the generations.
    protected void
    increaseGeneration(int value)
    This method increases the number of TS-MBFOA generations.
    void
    reproduction(Configurator bacterium)
    In the reproduction method, the bacteria are ordered based on the constraint management technique, eliminating the worst Sb - Sr bacteria and duplicating the best ones.
    protected void
    setCount(int count)
    Method that assigns value to the count.
    protected void
    setGeneration(int generation)
    Method that assigns value to the generation.
    void
    updateStepSize(Configurator bacterium, Problem problem)
    The updateStepSize method updates the TS-MBFOA step size.
