pub const BABYBEAR_POSEIDON1_PARTIAL_ROUNDS_16: usize = 13;Expand description
Number of partial rounds for BabyBear Poseidon1 (width 16).
Derived from the Gröbner basis bound in the Poseidon1 paper (Eq. 4, line 2) and the Poseidon2 paper (Eq. 1, R_GB term 3):
R_GB ≥ t − 7 + log_α(2) · min{κ/(t+1), log_2(p)/2} = 9 + 0.3562 · min{7.53, 15.5} = 11.682
With the +7.5% security margin (Section 5.4): ⌈1.075 × 11.682⌉ = 13.
