hash - Implementing Flajolet–Martin algorithm in Python
WebThe Flajolet–Martin algorithm is an algorithm for approximating the number of distinct elements in a stream with a single pass and space-consumption logarithmic in the … WebOur proof is based on [1]. We say that our algorithm is correctif 1 c ≤ F˜ F ≤ c (i.e., our estimate F˜ is off by at most a factor of c, from either above or below). The above proposition indicates that our algorithm is correct with at least a constant probability 1 − 3 c > 0. Lemma 1. Foranyintegerr ∈ [0,w],Pr[zk ≥ r] = 1 2r. Proof.
