A naive greedy algorithm produced only a maximal (not maximum) matching, leaving some hackers unhoused. By switching to a max-flow based algorithm (Edmonds-Karp or Hopcroft-Karp), the team achieved a 100% match rate for HackMIT 2015, compared to 95% with the greedy approach — demonstrating the real-world impact of choosing the right algorithm. ## Full article daily.dev links to this article rather than hosting it.
