The only reliable way is to break tings up into small parts for which it is possible to figure out the expected behavior and then run lots of tests on the parts, i.e., oversized unit testing @jasmine gray

E.g., if you plug in the data from 20 years ago, will it predict what the state of the system is today? If it can't do that, then no matter how faithfully the code implements the algorithm, the algorithm is useless.
