Method Details

compare

public int compare(EnhancedVector v1,
 EnhancedVector v2)

Compares two PopulationChangeVector objects.* for the fine grain Block Triangular Form. First vectors are compared at the number of non zero elements (h) Then the position of those elements based on right most nonzero Then the value at those positions, left to right leftmost non-zero is the smaller.

Specified by:

compare in interface Comparator<EnhancedVector>

Parameters:

v1 - the first vector to compare

v2 - the second vector to compare

Returns:

-1 if this < o, 0 if this = o, 1 if this > o
