The document "An Erasable High-Efficiency Filter Algorithm and Implementation Based on Bit Identification" introduces a novel approach to address the challenges faced by traditional Bloom filters, such as difficulty in deleting elements and high false positive rates. This algorithm utilizes an improved prefix tree structure to construct an erasable high-efficiency filter, effectively solving the issues encountered in traditional Bloom filters and achieving a false positive rate of 0. By optimizing performance strategies, the algorithm enhances the traditional R-way prefix tree based on bit identification, significantly reducing memory consumption. Experimental results demonstrate that this algorithm can efficiently complete string retrieval and filtering tasks while minimizing memory space utilization without compromising time complexity. Furthermore, it enables the deletion of filter elements and achieves a false positive rate of 0, making it suitable for high-concurrency system applications. The innovation presented in this study provides a valuable contribution to the field of filter algorithms, offering a more efficient and reliable solution for data processing and filtering in modern computing systems.
