The decision tree algorithm is a method used to evaluate alternatives and make decisions. It involves constructing a chart with various levels of “yes” or “no” questions to determine the best course of action. This chart can be used to answer questions related to whether or not one should accept a job offer, for example. It takes into account factors such as salary, benefits, commute time, and additional perks in order to help you make an informed decision. Each yes/no answer leads to another question, ultimately resulting in the best-fit decision being reached.
