Iteration Domains: Let's Draw Shapes

by Evan Conrad, February 26, 2018

An iteration domain is the total range of values that a program is iterating over.


Take the following code:

for (int i = 0; i < 6; i++) {
    for (int j = i; j < 10; j++) {
        // Do something

If we plot a point at every i and j value, we've mapped the "iteration domain" of the program:
