Nils J. Nilsson, in Artificial Intelligence: A New Synthesis, 1998 22.1.6 Backward Search Methods. We can search backward from a goal state using the STRIPS rules. To do so, we must regress goal wffs through STRIPS rules to produce subgoal wffs. The regression of a formula γ through a STRIPS rule α is the weakest formula γ' such that if γ' is satisfied by a state description before. This early research in the field of Artificial Intelligence was focused on exploring areas like problem-solving and symbolic methods. Moreover, it was only later, when the US Department of Defense took an interest in the technology that work began to train machines and computers to mimic human reasoning

ALP clausal logic, as a model of the LOT, can help. Forward chaining is a popular implementation strategy for expert systems, business and production rule systems. The opposite of forward chaining is backward chaining. Forward chaining starts with the available data and uses inference rules to extract more data (from an end user, for example) until a goal is reached The focus of this article will be on the concept called backpropagation, which became a workhorse of the modern Artificial Intelligence. Forward Pass. Forward pass is basically a set of operations which transform network input into the output space. During the inference stage neural network relies solely on the forward pass The results prove that the artificial neural network can work sufficiently as a knowledge-acquisition tool for the diagnosis problem. To apply the knowledge in the trained network, a reasoning strategy that hybridizes forward-and backward-reasoning schemes is proposed to realize the inference mechanism

In the early days of knowledge-based systems, the presentation and analysis were at two levels: 1) the primitive representation mechanisms (rules, frames, etc.) and their associated primitive inferencing mechanisms (forward and backward chaining, inheritance, demon firing, etc.), and 2) the problem description Artificial intelligence - Artificial intelligence - Reasoning: To reason is to draw inferences appropriate to the situation. Inferences are classified as either deductive or inductive. An example of the former is, Fred must be in either the museum or the café. He is not in the café; therefore he is in the museum, and of the latter, Previous accidents of this sort were caused by. backward chaining using a data-driven rules engine requires automatic generation of declarative goals. We implemented this in Inference Corporation's Automated Reasoning Tool (ART) in 1984. And we implemented it again at Haley a long time ago in a rules langauge we called Eclipse years before Java In information technology a reasoning system is a software system that generates conclusions from available knowledge using logical techniques such as deduction and induction.Reasoning systems play an important role in the implementation of artificial intelligence and knowledge-based systems.. By the everyday usage definition of the phrase, all computer systems are reasoning systems in that.
