The cyclomatic complexity of a function is an indication of the number of paths that can be taken during the execution of a function. Passport. To get the cyclomatic complexity of a program, simply represent it as a graph and count the cycles. But I'm a bit confused on how I could rewrite it in such way so it works. Improve this answer. Longer answer: "The cyclomatic complexity of a section of source code is the number of linearly independent paths within it." I've found a way to aggregate complexity from Cyclomatic Complexity that can offer some value when comparing two classes, or two projects.
