public class MongeElkan
extends AffineGap

The match method proposed by Monge and Elkan. They called this Smith-Waterman, but actually, this uses an affine gap model, so it's not Smith-Waterman at all, according to the terminology in Durban, Sec 2.3. Costs are as follows: mismatched char = -3, match = +5 (case insensitive), approximate match = +3, for pairings in {dt} {gj} {lr} {mn} {bpv} {aeiou} {,.}, start gap = +5, continue gap = +1

Method Detail

setScaling

public void setScaling(boolean flag)

If scaling is true, then distances are scaled to 0-1

setScaling

public void setScaling(java.lang.Double flag)

For interfacing with reflection in MatchExptScript. Scaling is true iff flag!=0.
