Hash tables are one of the oldest and simplest data structures for storing elements and supporting deletions and queries. Invented in 1953, they underly most computational systems. Yet despite their ...

High function, low cost—serious woodworking starts here. In this practical DIY project, I’ll show you how to transform a simple IKEA countertop into a fully functional double router table, perfect for ...

The original version of this story appeared in Quanta Magazine. Sometime in the fall of 2021, Andrew Krapivin, an undergraduate at Rutgers University, encountered a paper that would change his life.

A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible. Sometime in the fall of 2021, Andrew ...

Double hashing is designed to reduce clustering. It does this by calculating the stride for a given key using a second, independent hash function. Thus, two objects will have the same probe sequence ...

As we have seen in previous videos, it happens sometimes that two keys yield the same hash value for a given table size. This is called a “hash collision” or just “collision.” Why do hash collisions ...

Throughout the history of the WNBA, there have only been two triple-doubles recorded by a rookie. Both of those belong to Indiana Fever superstar Caitlin Clark. Clark made history earlier this season ...

Seventy years after the invention of a data structure called a hash table, theoreticians have found the most efficient possible configuration for it. About 70 years ago, an engineer at IBM named Hans ...
