Between Logic and Heuristic :: Calculus Mathematics Essays

Between pellucid system and Heuristic*ABSTRACT This article ingests to score a new type of logical calculi-logical heuristic densification which contains the marrow of reducing complete search. Such a heuristic component of calculus is reached with the help of meta-level means. The principal means for reducing search is structural data about information about contrary literals of formula. There be twain major approaches to studying the process of conclude (problem-solving). On one hand, it is obligatory to discover and investigate correct modes of reasoning in which the property of right is preserved. This task which can be formulated as the question what is a correct reasoning ( cogent evidence)? is considered in Logic. In order to decide this problem, Logic is based upon the concept of logical form. There is a exceptional syntactical method acting to deal with this conceptthe method of construction of a logical calculus. In this respect, the calculus in question is a raw disaster which guarantees the true conclusion under the true premisses. Thus, Logic (logical form) gives the perform for the question about correct reasoning the correct reasoning is a proof. But logical syntax, as a black box calculus, isnt interested in the real process of derivation building, in studying the question about methods of proof-search, in studying and construction a more manageable and efficient machinery of truth preserving. Availability of any method of exhaustive (complete) search, e.g. British museum algorithm, is quite enough for Logic (logical form). On the other hand, the process of problem-solving can be investigated in the light of the following(a) question how is it possible to build a piece of correct reasoning?. This task is considered in Heuristic. Heuristic investigates general principles and methods of problem-solving. computer Heuristic (computer heuristic method) is a system of rules (a rule) for essential reducing the complete search, i.e. he uristic methods are opposed to exhaustive search methods. The area of intersection of Logic and Computer Heuristic is proof-seach theory (PST), which investigates possible methods of problem-solving (how is it possible to build a proof?) in some calculus. PST deals with the heuristic component of proof systems. More precisely, the aim of proof-search theory can be defined as follows discovering, on the al-Qaida of a calculus and an entity in the calculus in question of the social structure of a possible derivation of this entity, a derivation which is interesting in some respect.(1) Thus, proof-search theory can be included into the logical pragmatic (look at Fig.
