Immune System Simulator 20XX

Similar to Day 15 we implement the rules precisely, paying attention to edge cases.

In particular during part two, it’s possible for a fight to end in a draw, if both armies become too weak to destroy any further units. As each fight is independent, we find the minimum boost value with a multithreaded parallel search.
