PSYCH 240 Lecture Notes - Lecture 18: Problem Solving, Power Law, Psych
Document Summary
Types of problems: well-structured, completely specific starting conditions, goal state, and methods for achieving the goal. Ill-structured i. e. geometry proofs: finding someone to marry, choosing a career, writing the best novel. Stages of problem solving: polya (1957, form a representation, construct a plan, execute plan, checking/evaluation, reformulate if you have not reached goal, problem solving concepts. Intermediate states: representation of problems, operators: actions that move between states, problem space: whole range of possible states and operators, only some of which will lead to goal state. The nine dot problem: there are 9 dots arranged in a square below, using no more than 4 lines, connect all the dots without lifting your pencil. Monk problem representation: text-based representation is difficult, modify representation to an isomorphic problem: two monks. Paper folding representation: picture a large piece of paper, 1/100 of an inch thick.
