This computer science video describes the fundamental principles of the hash table data structure which allows for very fast insertion and retrieval of data. It covers commonly used hash algorithms for numeric and alphanumeric keys and summarises the objectives of a good hash function. Collision resolution is described, including open addressing techniques such as linear and quadratic probing, and closed addressing techniques such as chaining with a linked list.

Excellent video! I spent the last half of my 34 years in IT working with the Advanced Pick and Unidata databases which depend heavily upon hashed access. The key to efficiency is selecting the right modulus when creating your file. Too small and you get too many collisions, too large and you waste space. The multivalue database concept goes back to the mid-60’s, but it is still hard to beat for efficiency and ease of use.

@stephan553
@stephan553 4 года назад
One _very important_ case against open addressing is that any case where the key is not contained in the hash map can only be resolved in O(n) time, that is a time linear to the length of the whole map. Closed addressing can resolve this by simply traversing the much shorter list at the respective key. No matter if databases, caches or many other use cases, looking up a missing key is a very common situation.
@your-mom-irl
@your-mom-irl Год назад
That shouldn't matter much if the load factor is kept low and the hash function has a good distribution, but yeah it is a possibility lol A uniform distribution with 50% load factor will give you an average of just 1 miss

Excellent, crystal clear, perfectly animated and optimally paced. Many thanks ! What I missed were some simple ideas to improve the hash function to reduce collisions. I could think of factoring in the position of a letter, so that 'Leo' doesn't collide with 'Loe'. Maybe also the length of the string though that's of no use in this particular example. Also it would be great to have some examples of how to choose between closed and open (and the different variants of open).
