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 ...
