Methods of problem solving: use of algorithms • Well-defined problems: - 3 elements • All three have to be clear - Clear starting point • So you know exactly what your dealing with - Clear goal • So you know exactly when the problems solved - Clear set of operations • - Rubixs Cube • Starting point - Messed up tiles • Goal 2
Tuesday, October 9, 2018 - Make the all the colors on one side and the others on the other • Algorithm - Step by step rhythm that guarantees a solution - Methods of Problem solving: Use of Heuristic Devices • Ill-defined problem - At least one of the 3 elements is unclear • dont guarantee a solution • Simple rules that usually but don’t always give us a solution - Methods of Problem Solving: Use of Analogies • Take the solution to a previous problem and apply it to a new problem • If the new problem and the old problem are similar under the surface but look really di ff erent it’d be hard that the solution applies to one and not the other?? - Factors that a ff ect problem solving • Expertise - Easier to fix the problem if you are already familiar with it • Mental sets - Two problem that you think are similar to each other but actually aren’t - The issue is if you think it is similar and try to apply to anther problem it doesn’t work • Incubation - A problem you’re trying to solve and you step back from the problem and then the solution just pops in your head - It is easier to solve problem if you step back -
