One of the most popular methods of knowledge representation are the fuzzy rules. One of the ways of representation of fuzzy rules is the functional representation. From over eight decades a number of different fuzzy implications have been described, e.g. [5]-[9]. This leads to the following question: how to choose the proper function among basic fuzzy implications. This paper is a continuation of study [15], where we proposed a new method for choosing implications in backward reasoning. Here we presented a way of simplify the analysis by skipping Yager fuzzy implication. Key words: fuzzy logic, fuzzy implications, inverted fuzzy implications, backward reasoning
