Forward chaining (or forward reasoning) is one of the two main methods of reasoning when using an inference engine and can be described logically as repeated application of modus ponens. Forward chaining is a popular implementation strategy for expert systems, business and production rule systems. The opposite of forward chaining is backward ...
Inference engines work primarily in one of two modes either special rule or facts: forward chaining and backward chaining. Forward chaining starts with the known facts and asserts new facts. Backward chaining starts with goals, and works backward to determine what facts must be asserted so that the goals can be achieved. [1]
Backward chaining is implemented in logic programming by SLD resolution. Both rules are based on the modus ponens inference rule. It is one of the two most commonly used methods of reasoning with inference rules and logical implications – the other is forward chaining. Backward chaining systems usually employ a depth-first search strategy, e ...
Chaining is the process of teaching the steps of a task analysis. The two methods of chaining, forward chaining and backward chaining, differ based on what step a learner is taught to complete first. In forward chaining, the ABA practitioner teaches the learner to independently complete the first step and prompts the learner for all subsequent ...
A common approach is to implement production systems to support forward or backward chaining. Each rule ('production') binds a conjunction of predicate clauses to a list of executable actions. At run-time, the rule engine matches productions against facts and executes ('fires') the associated action list for each match.
Moving backward is also common in sports — think soccer players and referees. There are even some backward running and walking races, plus people moving in reverse while competing in famous ...
Cwm, a forward-chaining reasoner used for querying, checking, transforming and filtering information. Its core language is RDF, extended to include rules, and it uses RDF/XML or N3 serializations as required. Drools, a forward-chaining inference-based rules engine which uses an enhanced implementation of the Rete algorithm.
President Joe Biden announced he would commute the sentences of 37 individuals on federal death row. Here's what that means.
