Scaling in reinforcement learning Technical Report TR Reactive behavior, learning, and anticipation. A role for anticipation in reactive systems that learn. An example is the skillful way in which his terrier Tony opened the garden gate, easily misunderstood as an insightful act by someone seeing the final behaviour.
Lloyd Morgan, however, had watched and recorded the series of approximations by which the dog had gradually learned the response, and could demonstrate that no insight was required to explain it. Edward Thorndike was the initiator of the theory of trial and error learning based on the findings he showed how to manage a trial-and-error experiment in the laboratory. In his famous experiment, a cat was placed in a series of puzzle boxes in order to study the law of effect in learning. Thorndike's key observation was that learning was promoted by positive results, which was later refined and extended by B.
Skinner 's operant conditioning. Trial and error is also a heuristic method of problem solving, repair , tuning, or obtaining knowledge. In the field of computer science , the method is called generate and test. In elementary algebra, when solving equations, it is "guess and check". This approach can be seen as one of the two basic approaches to problem solving, contrasted with an approach using insight and theory. However, there are intermediate methods which for example, use theory to guide the method, an approach known as guided empiricism.
The trial and error approach is used most successfully with simple problems and in games, and it is often the last resort when no apparent rule applies. This does not mean that the approach is inherently careless, for an individual can be methodical in manipulating the variables in an attempt to sort through possibilities which could result in success. Nevertheless, this method is often used by people who have little knowledge in the problem area. The trial-and-error approach has been studied from its natural computational point of view .
The strategies are:. Note the tacit assumption here that no intelligence or insight is brought to bear on the problem.
Trial and error in the evolution of cognition.
However, the existence of different available strategies allows us to consider a separate "superior" domain of processing — a "meta-level" above the mechanics of switch handling — where the various available strategies can be randomly chosen. Once again this is "trial and error", but of a different type.
Ashby's book develops this "meta-level" idea, and extends it into a whole recursive sequence of levels, successively above each other in a systematic hierarchy. On this basis he argues that human intelligence emerges from such organization: relying heavily on trial-and-error at least initially at each new stage , but emerging with what we would call "intelligence" at the end of it all. Thus presumably the topmost level of the hierarchy at any stage will still depend on simple trial-and-error.
After all, it is part of Piagetian doctrine that children learn by first actively doing in a more-or-less random way, and then hopefully learn from the consequences — which all has a certain to Ashby's random "trial-and-error". Traill , espec. Table "S" on p. In the Ashby-and- Cybernetics tradition, the word "trial" usually implies random-or-arbitrary , without any deliberate choice. Among non-cyberneticians, however, "trial" will often imply a deliberate subjective act by some adult human agent e. Of course the situation becomes even more confusing if one accepts Ashby's hierarchical explanation of intelligence, and its implied ability to be deliberate and to creatively design — all based ultimately on non-deliberate actions.
The lesson here seems to be that one must simply be careful to clarify the meaning of one's own words, and indeed the words of others. When an experiment was not successful, he was happy to admit that he now knew the things that did not work. Trial and error was Edison's most successful means of invention. Most [ who? Today, the approach of voodoo programming is an usage where code is composed with trial and error until something which produces the desired output is found.
It is possible to use trial and error to find all solutions or the best solution, when a testably finite number of possible solutions exist. To find all solutions, one simply makes a note and continues, rather than ending the process, when a solution is found, until all solutions have been tried. To find the best solution, one finds all solutions by the method just described and then comparatively evaluates them based upon some predefined set of criteria, the existence of which is a condition for the possibility of finding a best solution.
Also, when only one solution can exist, as in assembling a jigsaw puzzle, then any solution found is the only solution and so is necessarily the best. Trial and error has traditionally been the main method of finding new drugs, such as antibiotics. Chemists simply try chemicals at random until they find one with the desired effect. In a more sophisticated version, chemists select a narrow range of chemicals it is thought may have some effect using a technique called structure-activity relationship.

The latter case can be alternatively considered as a changing of the problem rather than of the solution strategy: instead of "What chemical will work well as an antibiotic? Trial and error is also commonly seen in player responses to video games - when faced with an obstacle or boss , players often form a number of strategies to surpass the obstacle or defeat the boss, with each strategy being carried out before the player either succeeds or quits the game.
