WebPython implementation of the dgim algorithm: Compact datastructure to estimate the number of "True" in the last N elements of a boolean stream. WebThe DGIM algorithm allows us to answer the question with a logarithmic amount of memory, and with tunable precision. More precisely, for a given precision 1/m, the needed amount of memory is O (m log (N)²). Just to outline, log (N)² (base 2) is a ridicously low number compared to N, for big N. For example, if N is 80 bilions, log (N)² is 1311.
