The m + n + 1 column contains the weight that is to be applied to the rule. The weight must be a number between zero and one and is generally left as one.
To understand how weights are used, see here and search for "weight".
The m + n + 2 column contains a 1 if the fuzzy operator for the rule's antecedent is AND. It contains a 2 if the fuzzy operator is OR. (so that's the connection).
