Class SmallestMin<T extends IntVar>

  • Type Parameters:
    T - type of variable being used in the search.
    All Implemented Interfaces:
    ComparatorVariable<T>
    public class SmallestMin<T extends IntVar>
extends java.lang.Object
implements ComparatorVariable<T>
    Defines a SmallestMin comparator for variables. It prefers variables which have smaller minimal value in their domain.
    Version:
    4.8

      • compare

        public int compare​(float left,
                   T var)
        Description copied from interface: ComparatorVariable
        It compares the baseline metric to the variable metric.
        Specified by:
        compare in interface ComparatorVariable<T extends IntVar>
        Parameters:
        left - the baseline for comparison.
        var - variable which is compared to baseline.
        Returns:
        1 if metric is larger than variable, 0 if equal, -1 if baseline is smaller.

      • compare

        public int compare​(T leftVar,
                   T rightVar)
        Description copied from interface: ComparatorVariable
        It compares the metric of the left variable against the right one.
        Specified by:
        compare in interface ComparatorVariable<T extends IntVar>
        Parameters:
        leftVar - left variable
        rightVar - right variable
        Returns:
        1 if metric for left variable is greater, 0 is they are equal, -1 if smaller.

      • metric

        public float metric​(T o)
        Description copied from interface: ComparatorVariable
        It returns the metric of the variable given according to the comparator.
        Specified by:
        metric in interface ComparatorVariable<T extends IntVar>
        Parameters:
        o - variable for which metric is computed.
        Returns:
        the metric of the variable according to the comparator.
