General problem solving. 1 Overview of Expert System Technology 279 8. 215) represents a more complex approach to problem-solving that requires a deeper level of understanding about mathematics. The problem must be complex enough so the best student in the class is not certain ho to sol e itcertain how to solve it. Arguing for and against a particular problem-solving strategy is a useful way of determining the pros and cons of each, and deciding which solution you’ll implement first. For Exercises 1-6, match the problem solving strategy with the definition or example. Both merge sort and quicksort employ a common algorithmic paradigm based on recursion. Imagine if you could solve a problem once and it would go away. By repeatedly asking the question “why” on a problem, you can dig into the root cause of a problem, and that’s how you can find the best solution to tackle the root problem once and for all. The early work on problem solving was concerned with problems that were puzzles or games such as the Tower of Hanoi task (see below for a description of the task). 34 Chapter 3 Algorithmic Problem Solving 3. Problem Solving Meetings are oriented around solving either a specific or general problem, and are perhaps the most complex and varied type of meetings. However, in the standard way the adding is done at the same time as multiplying. The Six-Step Problem-Solving Process is an easy approach to dealing with issues and problems that you face.
