public class FuzzyRule
extends java.lang.Object

Fuzzy rule Rule: If (x1 is termX1) AND (x2 is termX2) .... Then (y1 is termY1) AND (y2 is termY2) [weight: 1.0] Notes: - "If" clause is called "antecedent" - "then" clause is called "consequent" - There may be 1 or more antecedents connected using a 'RuleConnectionMethod' (e.g. AND, OR) - As there are many ways to implement 'AND' and 'OR' connectors, you can customize them
