"WebThe Cuckoo Graph Claim 1: If x is inserted into a cuckoo hash table, the insertion fails if the connected component containing x has two or more cycles. Proof: Each edge represents an element and needs to be placed in a bucket. If the number of nodes (buckets) in the CC is k, then there must be at least k + 1 elements (edges) in that CC to have two cycles. " - Hopscotch hashing visualization

Hopscotch hashing is a scheme in computer programming for resolving hash collisions of values of hash functions in a table using open addressing. It is also well suited for implementing a concurrent hash table. Hopscotch hashing was introduced by Maurice Herlihy, Nir Shavit and Moran Tzafrir in 2008. The name is derived from the sequence of hops that characterize the table's insertion algorithm.
