WebLinear Probing has the best cache performance but suffers from clustering. Quadratic probing lies between the two in terms of cache performance and clustering. Double caching has poor cache performance but no clustering. Load Factor (α)- Load factor (α) is defined as- In open addressing, the value of load factor always lie between 0 and 1. WebThe main trade offs between these methods are that linear probing has the best cache performance but is most sensitive to clustering, while double hashing has poor cache …
