hidden conditions in the child nodes Alphanode are met, then exactly matches a rule, forming the agenda to join the conflict collection, to match all the rules, The result part of the match rule is then executed according to the priority of the rule, and the fact data is changed.===> to the right (another rule is matched), if all of the child nodes alphanode the hidden conditions are met, then exactly match a rule, forming an agenda to join the confl

This is a creation in Article, where the information may have evolved or changed. Rete Algorithm IntroductionI. Overview of ReteRete algorithm is a forward rule fast matching algorithm, and its matching speed is independent of the number of rules. Rete is Latin, which corresponds to the net in English, that is, the Internet. The

execution rule (conflict), which means that more than one rule is activated at the same time, the conflicting rule is placed in the conflicting collection.Resolve the conflict by placing the activated rules in the order of agenda.Executes the rules in agenda using the execution engine. Repeat steps 2 through 5 until you have finished executing the

rules. The "chained" response to this rule is entirely driven by data in the workspace.The efficiency of the rule condition matching determines the performance of the engine, the engine needs to quickly test the data objects in the workspace, find the eligible rules from the loaded rule set, and generate the rule exec

functionality, they have different priorities. "" takes precedence over "| |", "" and "| |" Also takes precedence over ",". However, it is recommended that the "," delimiter be preferred, as it is more conducive to reading comprehension and engine optimization operations. At the same time, the comma delimiter cannot be mixed with other operators, such as:// Compile Error // Use this method instead of Person ((Age > weight >) | | height > 2)View Code
