How Adaptive K Works

Small tournaments (n ≤ 200)

Full round-robin — every player faces every other player exactly once. K = n − 1. The configured K value is ignored.

Large tournaments (n > 200)

The configured K is clamped to [49, 99] and used directly. Players are paired using a Feistel-network permutation (deterministic, no duplicates, O(1) memory per match).
