Subject: [bitcoin-dev] Minimizing the redundancy in Golomb Coded Sets
Date: Fri, 25 May 2018 10:54:17 -0700 [thread overview]
Message-ID: <CAPg+sBgywj6PgijmSNkYYkKKQuek2g9-cSy6GJBpV+=gom7LfQ@mail.gmail.com> (raw)
Hi all,
I spent some time working out the optimal parameter selection for the
Golomb Coded Sets that are proposed in BIP158:
https://gist.github.com/sipa/576d5f09c3b86c3b1b75598d799fc845
TL;DR: if we really want an FP rate of exactly 1 in 2^20, the Rice
parameter should be 19, not 20. If we don't, we should pick an FP rate
of 1 in a 1.4971*2^B. So for example M=784931 B=19 or M=1569861 B=20.
Cheers,

Pieter
