Each edge of the bipartite graph has a weight equal to an index of a hash function associated with that edge. The method also includes determining a minimal weight perfect matching of the bipartite graph and generating an XORSAT filter using the minimal weight perfect matching of the bipartite graph, such that a minimal perfect hash function can be performed on an element by querying the XORSAT filter for a result associated with the element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods of minimal perfect hashing with XORSAT filters","description":"A computer-implemented method of constructing a minimal perfect hash function includes selecting a set H of k hash functions over a set Y of n keys and building a bipartite graph from keys to hash val","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11997186","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
