What is back chaining?

Back chaining is a logic system used by artificial intelligence systems. It is designed to solve the problem by working back from the final goal through a series of rules. This approach can use a wide range of systems, from programs that solve chess games to algorithms used to identify unknown objects. The basis requires robust programming with a set of logical and useful induction rules that the system can use to accurately move a number of ways to achieve a solution. The system works back within the rules to determine how the final goal could be reached. In backward induction used programs that solve chess games, for example, a computer can take the position of pieces and pass through a number of IF-thorn commands to determine the probable course of movements in the game. The computer can also use backward chaning to explore other possible solutions and branches that could occur during the game to change the result.

The

systems that use back chaining may have rules that differ in complexity, depending on the type of work they have to do. For example, a system capable of identifying flowers may require a large set of branching options to determine exactly the species it looks at. This could start with a series of color -related statements, to move flowers, the number of petals, leaves and other characteristics, and determine the identity of the questions corresponding to the flower in every step to determine the final answer. Errors in this process could lead to identification errors.

This reasoning system requires simple logic. The system examines the fact, determines whether it is suitable for the product, and then takes the next step. If the reality of not corresponding to the information is incorrect and the back chain logic can throw away this fact and others that could turn off. Facts that fit, allow the program to work with logic and explore branching facts to find out to find out whichRá best suits. This can work well for different tasks.

Artificial intelligence is not the only entity that can use back chaining. Scientists who work with primates note that some species seem to use this logical method to solve problems. This illustrates the capacity to understand the problems and the development of the system for their solution.
