commit: bd0517ae29

in UnifyPair.java

public Set getSubstitution() {
return new HashSet<>(substitution);
}

public Set getAllSubstitutions () {
Set ret = new HashSet<>();
ret.addAll(new ArrayList<>(getSubstitution()));
if (basePair != null) {
ret.addAll(new ArrayList<>(basePair.getAllSubstitutions()));
}
return ret;
}

geändert Könnte das Problem lösen:

Die gleichen Substitionen wurden über getSubstitution() in verschiedenen Pairs benutzt.
