Knuth (AoCP 6.4) more or less waves away the `open hashing' strategy,
where you resolve conflicts by allocating a linked list outside the hash
table. He devotes almost all of that section to `closed hashing',
investigating linear probing and chaining as ways of storing the
conflicting items elsewhere in the table.


Personally, I don't see the problem with open hashing.


So, was closed hashing born of necessity in the days when memory was at
a premium and you needed to keep track of every last byte yourself?


What's used these days?
