Method Detail

resolveCumulativeConclusions

Value resolveCumulativeConclusions(java.util.LinkedList<Value> ambiguousValues)

This method is used when there is several ambiguous values in the memory and all of the values are considered cumulative in terms of the certainty factors algebra. This is the case, when the values are assigned by different XTT2 tables.

Parameters:

ambiguousValues - set of ambiguous values from which the true value has to be extracted, or calculated

Returns:

the resulting value that still may not be certain, yet is is less ambiguous then the set

                                                                                                          ConflictSetResolution csr)
                                                                                                   throws NotInTheDomainException

This method is used when there is a need to select rules to fire from ambiguous rule set. It can be thought of as a conlict set resolution on the level of uncertainty. When two or more rules have the same certainty level assigned, then the standard conflict set resolution mechanism should be used.

Parameters:

ambiguousRules - set of rules that satisfy minimal satisfiability threshold, yet there is still uncertain which of them should actually be fire

wm - working memory component that should be used to evaluate rules decisions

csr - conflict set resolution mechanism that should be applied in case when to or more rules have the same certainty level

Returns:

the set of rules that should be executed.

Throws:

NotInTheDomainException
