In computer science, Dancing Links, also known as DLX, is the technique suggested by Donald Knuth to efficiently implement his Algorithm X. Algorithm X is a recursive, nondeterministic, depth-first, backtracking algorithm that finds all solutions to the exact cover problem.

As the remainder of this article discusses the details of an implementation technique for Algorithm X, the reader is strongly encouraged to read the Algorithm X article first.

Knuth observed that a naive implementation of his Algorithm X would spend an inordinate amount of time searching for 1's.

In Algorithm X, rows and columns are regularly eliminated from and restored to the matrix.
