The Dancing Links algorithm solving a polycube puzzle. In computer science, dancing links (DLX) is a technique for adding and deleting a node from a circular doubly linked list. It is particularly useful for efficiently implementing backtracking algorithms, such as Knuth's Algorithm X for the exact cover problem. [1]
Linked list implementations, especially one of a circular, doubly-linked list, can be simplified remarkably using a sentinel node to demarcate the beginning and end of the list. The list starts out with a single node, the sentinel node which has the next and previous pointers point to itself. This condition determines if the list is empty.
A webring (or web ring) is a collection of websites linked together in a circular structure, and usually organized around a specific theme, often educational or social. [1] They were popular in the 1990s and early 2000s, particularly among amateur websites.

San Francisco, a hub for innovation and tech, takes the third spot on the list. The median home size in the area is 1,309 square feet. Homes sold for an average price of $947 per square foot.
A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation. It operates by connecting unallocated regions of memory together in a linked list, using the first word of each unallocated region as a pointer to the next. It is most suitable for allocating from a memory pool, where all objects have the same size ...
