When the load of the hash table grows too large in proportion to the hash table size, you increase the size of the hash table to improve performance. When the load is too large is dependant on a predetermined value, the load factor.
How do you refer to the term that decides when to decrease the size of the hash table when the load is too small?
if (load > size * 0.75)
increase_size();
if (load < size * 0.25)
decrease_size();
Here 0.75
is the load factor of the hash table. What do you call 0.25
?
