I built a jet clustering algorithm based on the anti-kt model used in professional analyses here at CERN. Mine is, of course, more rudimentary but was still quite fun to make. The histogram attached here shows the distribution of the algorithm's results for number of jets. The input was 10,000 events from the MC jet program I built earlier with two jets sent in opposite directions. The histogram clearly shows a peak at 2, which implies that the algorithm is working.
