WebSep 22, 2016 · Once we have carried out this backward reasoning, we can easily reverse the steps to construct a proof using forward reasoning. We now give this proof. Suppose that x and y are distinct positive real numbers. Then (x − y)2 > 0 because the square of a nonzero real number is positive. Because (x − y)2 = x2 - 2xy + y2 > 0.

WebMay 14, 2024 · A backward chaining algorithm is a form of reasoning, which starts with the goal and works backward, chaining through rules to find known facts that support the goal. Properties of Forward-Chaining: It is known as a top-down approach. Backward-chaining is based on modus ponens inference rule. In backward chaining, the goal is broken into … WebForward and backward reasoning The process we just followed is called forward reasoning. We simulated the execution of the program, considering each statement in the order they would actually be executed. The disadvantage of forward reasoning is that the assertions may accumulate a lot of irrelevant facts as you move through the program.
