WebUsing Morris' algorithm, the counter represents an "order of magnitude estimate" of the actual count. The approximation is mathematically unbiased. To increment the counter, a … WebThis is optimal, matching the straightforward protocols where the witness is either empty, or speci es all the elements of S. ... We demonstrate the power of these lower bound techniques by proving optimal lower bounds for the approximate counting problem, which captures the following task. Given a nonempty nite set S [N] := f1;:::;Ng, estimate ...
