1. In inductive reasoning, if all possible situations of a certain kind of event are investigated one by one and a general conclusion is drawn, then this conclusion is reliable. This inductive method is called enumeration. Enumeration method is to use the characteristics of high speed and high accuracy of computer to test all possible situations and find out the answers that meet the requirements, so enumeration method sacrifices time for the comprehensiveness of the answers.

2. In the theory of mathematics and computer science, enumeration of sets is a program that lists all members of some finite sequence sets, or counts a specific type of objects. These two types often (but not always) overlap.
