  • The closest thing that I can think of that comes close to whatever “structural complexity of algorithms” means is cyclomatic complexity, which I never touched on.

  • At a high level, we determine the value of cyclomatic complexity by counting the number of decisions made in our source code.

  • Essentially, with cyclomatic complexity, higher numbers are "bad" and lower numbers are "good".

  • We use cyclomatic complexity to get a sense of how hard any given code may be to test, maintain, or troubleshoot as well as an indication of how likely the code will be to produce errors.
