A Decision Tree
A simple decision tree with just two paths: one that shows a tick and another that shows a cross

Decision trees allow people and computers to make decisions whereby given criteria are classified into yes/no or true/false answers. (Imagery supplied by bsd555/iStock via Getty)
Objectives
Plan an artificial intelligence algorithm using a decision tree.
Create a decision tree that helps individuals select which mobile phones to buy, based on at least two criteria.
​
Your Goal
For some people, choosing a new mobile phone can be overwhelming because there are so many different kinds to choose from. You have decided to create an application that will make choosing a mobile phone easier. The application will suggest the mobile phone that is most suitable for the individual’s needs.

Your goal is to design a decision tree that will suggest which of four mobile phones an individual should buy (mobile phone A, B, C, or D).

There are of course certain criteria that you need to consider. Your first task is to define the two criteria to be considered. Each criteria should have a yes or no answer, or at least a two path answer, such as two operating systems. Some sample criteria you might use are here.

Must it have a touch screen (yes or no)?
Do I need a high-quality camera (yes or no)?
What operating system do I want (a choice of two)?
Do I want to commit to a contract (yes or no)?
Your goal is, therefore, to draw a decision tree that suggests whether an individual should buy mobile phone A, B, C, or D based on their budget and the quality of the phone’s camera.
