Load Factor is a measure of how full the hash table is allowed to get before its capacity is automatically increased which may cause a collision. When collision occurs, there are two simple solutions: Chaining and Linear Probe.

WebA critical influence on performance of an open addressing hash table is the load factor; that is, the proportion of the slots in the array that are used. As the load factor increases … WebThe quantity α is called the load factor of the hash table. If the set implementation used for the buckets has linear performance, then we expect to take O (1+α) time to do add, remove, and member . To make hash tables work well, we ensure that the load factor α never exceeds some constant αmax, so all operations are O (1) on average .
