A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible.
In the article, x is not the size of the hash table, it is the inverse of the table’s filling fraction. A 1000-element table that is 90% full has x=10, N=1000.
Since they’re not discussing scaling of data sizes, would be confusing to use O(N) notation or people would make that assumption.
