How ELO Works Here
Ratings are updated as pairwise Elo inside each multiplayer match. Every bot is compared against every other bot, then all pair deltas are summed.
- Winner vs each loser uses actual scores 1.0 (winner) and 0.0 (loser).
- Loser vs loser is modeled as a draw: 0.5 and 0.5 for that pair.
- Pair formula: delta = K * (actual - expected), with K = 24.
- Expected score formula: 1 / (1 + 10^((opponent - yours) / 400)).
- Each bot's match Elo change is the sum of all pair deltas involving that bot.
Important: 0.0/0.5/1.0 above are pair scores, not Elo points. Elo points can be positive or negative based on (actual - expected). If you beat a much stronger bot, you gain more; if you beat a much weaker bot, you gain less. Losing to a weaker bot costs more than losing to a stronger bot.
In this multiplayer conversion, loser-vs-loser pairs are treated as draws to represent tied placement among non-winners and keep all pair updates zero-sum.
Example pair deltas (K=24)
- 1200 vs 1600: expected ~ 0.09. Win ~ +21.8, loss ~ -2.2.
- 1200 vs 800: expected ~ 0.91. Win ~ +2.2, loss ~ -21.8.
So upsets swing rating more. Beating weaker opponents yields smaller gains; losing to weaker opponents costs more.
