摘要: A bloom filter is a space-efficient data structure allowing membership queries over sets with allowable errors. It widely used in databases, networks, and distributed systems. This paper presents novel filter, called basket (BBF). The BBF deals different elements set depending on their query invalidation cost, by clustering into baskets. total cost function defined. In order to minimize the genetic algorithm employed find optimal number of hash functions for every basket. Simulation results show that, has 40% lower than standard filters under same executing time.
