   @chenjunjiedada I'm interested in how you arrived at the formula for the optimal number of bits. Can you please elaborate on this? After reading the referenced paper on it (http://algo2.iti.kit.edu/documents/cacheefficientbloomfilters-jea.pdf) I'm unclear as to which equation you used from that paper or if you used another one.  We're attempting to implement this algorithm in a different language. Thank you.
