  • PROBLEM SPACE THEORYTHEORY of SPACE of RESOLUTION of PROBLEM Allan Newell & Herb Simon 1950 LADY SIMEIAStratigiki of resolution of problem.Space of resolution of problem.

    - initial situation - final situation - the all intermediary katastaseisOi persons create corresponding intellectual situations in their brain in order to they untie him.INTELLECTUAL KATASTASEISNoitikes situations of knowledge in the brain lyti.Initial situation Final situation (goal).Search of likely new situations.Telestes of passage.Strategies of passage in the final situation -(Heuristics).Intermediary solutions.What makes the problem difficult.The way that is given in lyti.The ypokeimeniki knowledge lyti.The size of space of resolution.The method that it uses lytis in order to it investigates the space of resolution.The intermediary solutions that are determined or no in the problem.General Problem Solver Newell, Shaw, & Simmon 1958,1960.Calculating model of resolution problimatonOi situations of knowledge are kept in the memory of work.The effects teleston on the situations knowledge are kept in the long-lasting memory. Algorithms & StratigikesOi algorithms solve always a problem examining the ALL likely situations of problem up to the achievement of objective.The strategies cannot guarantee the resolution of problem, him they make however in smaller time and with least labour. StratigikesStin beginning lytis learns general strategic independent from the problem (domain-independent srategies) Eg. reject of rains epanalipsisMe this knowledge learns how it resolves the particular problem. (domain-specific heuristics).ISOMORFISMOSDyo problems is isomorfika when exists antistoichisi to-between their their space of resolution and teleston.
