All Implemented Interfaces:

SepsetProducer

public class SepsetsConservative
extends Object
implements SepsetProducer

Provides a SepsetProcuder that selects the first sepset it comes to from among the extra sepsets or the adjacents of i or k, or null if none is found. This version uses conservative reasoning (see the CPC algorithm).
