Linked list

	Linked list (Site not responding. Last check: 2007-10-29)
		A linked list is one of the simplest data structures of computer programming.
		Linked lists permit insertion and removal of nodes at any point in the list in O(1) time.
		This link points to the next node in the list, or to a null value if it is the last node.

	Linked List - GPWiki
		A linked list is a data structure where every element contains both a 'value' and a link/reference/pointer to a 'next' element (and sometimes also one to a 'previous' element).
		The whole list is represented by a pointer/reference/link to the first element of the list (or a structure encapsulating this).
		The three major types of linked lists is the default single linked list, then there is the doubly-linked list, and the final major type is the circular linked list.

	Linked list - Wikipedia, the free encyclopedia
		Linked lists permit insertion and removal of nodes at any point in the list in constant time, but do not allow random access.
		Linked lists were developed in 1955-56 by Allen Newell, Cliff Shaw and Herbert Simon at RAND Corporation as the primary data structure for their Information Processing Language.
		Linked lists are used as a building block for many other data structures, such as stacks, queues and their variations.

	Finding a Loop in a Singly Linked List
		A singly linked list is made of nodes where each node has a pointer to the next node (or null to end the list).
		A singly linked list is often used as a stack (or last in first out queue (LIFO)) because adding a new fist element, removing the existing first element, and examining the first element are very fast O(1) operations.
		Common operations on a singly linked list are iterating through all the nodes, adding to the list, or deleting from the list.

	Reversible Linked Lists
		Linked lists and doubly linked lists are the first data structure anybody learns about formally.
		Once you had filled it, you could then unlink the user's line from that list and link it to the other half of the original perimeter, to be used as the new perimeter of the playable screen.
		The only trouble is, you need the list to be linked in the opposite order for the two uses, so you either have to construct a second copy pointing the other way, or use reversible lists.

	Tree List Recursion Problem
		The circular doubly linked list is a standard linked list with two additional features...
		"Doubly linked" means that each node has two pointers -- the usual "next" pointer that points to the next node in the list and a "previous" pointer to the previous node.
		We'll use the convention that a null pointer represents a list with zero elements.

	GameDev.net - Balanced binary search tree with a doubly linked list in C++
		Combining the doubly linked list with the red-fl tree results in a data structure that can have duplicates and has a fast and ordered traversal.
		The doubly linked list is a basic data structure and plenty of information about it is available on the web.
		Link the new element (1) in the list before the parent (3).

		One difficulty with the singly linked lists is that if we are poiting to a specific node, say p, then we can move only in the direction of the links.
		Set the forward link member of the new node to the node pointed Set the backward link member of the current node to the new node.
		Change the link of the backward and forward pointers to the link of the item to be deleted.

	A Memory-Efficient Doubly Linked List
		In a two-node list, the previous node to the StartNode is NULL and the next node is the EndNode.
		Inserting a node in an existing doubly linked list requires pointer fixing of three nodes: the current node, the next node of the current node and the new node.
		For 20,000 nodes the memory being used for the whole list is 160,000 bytes, and for 10,000 nodes it is 80,000 bytes.

	LinkedList (Java 2 Platform SE v1.4.2)
		These operations allow linked lists to be used as a stack, queue, or double-ended queue (deque).
		Operations that index into the list will traverse the list from the begining or the end, whichever is closer to the specified index.
		If the list fits in the specified array with room to spare (i.e., the array has more elements than the list), the element in the array immediately following the end of the collection is set to null.

	Doubly-Linked Lists (Site not responding. Last check: 2007-10-29)
		Doubly-Linked Lists -- linked lists containing integer values or pointers to data, with the ability to iterate over the list in both directions.
		List elements are allocated in blocks using a GListAllocator, which is more efficient than allocating elements individually.
		If this is negative, or is larger than the number of elements in the list, the new element is added on to the end of the list.

	Linked list - DmWiki
		At its most basic level, a linked list is a data structure consisting simply of a series of node structures, which are linked to each other.
		For this reason, linked lists are not appropriate if you need random access to various members.
		With a doubly linked list you just need to add a little extra code to set up the prev; pointers too.

	CS 46B Ms Fecteau Doubly Linked Lists (Site not responding. Last check: 2007-10-29)
		In a doubly linked list, each node keeps track of its previous node, in addition to its next node.
		Java's doubly linked list iterator defines its remove and set operations in terms of the last node passed over by the iterator.
		When converting the singly linked list iterator methods to doubly linked list iterator methods, we will have to make several changes.

	Doubly-Linked Lists
		Doubly-Linked Lists — linked lists containing integer values or pointers to data, with the ability to iterate over the list in both directions.
		Using these pointers it is possible to move through the list in both directions (unlike the Singly-Linked Lists which only allows movement through the list in the forward direction).
		List elements are allocated from the slice allocator, which is more efficient than allocating elements individually.

	Linked List Tutorial
		A linked list is simply a chain of structures which contain a pointer to the next element.
		A list item has a pointer to the next element, or to 0 if the current element is the tail (end of the list).
		Singly linked lists are useful data structures, especially if you need to automatically allocate and de-allocate space in a list.

	CocoaDev: DesignDoublyXORLinkedList
		Lists can also be implemented with just one of these pointers, saving a pointer's worth of memory for every element in the list but losing the constant insertion, access and deletion to one end of the list.
		The cost of a doubly-linked list is three pointers per element in the list: the previous and next pointers, and a pointer to the object stored at each entry.
		For this we actually have the DeQue -- the advantage of a double linked list is constant time removal and insertion at any place in the list (including constant time list splicing or splitting), which the XOR trick does not allow us.

		Note: The first item, or head, is accessed from a fixed location, called a "head pointer." An ordinary linked list must be searched with a linear search.
		Average search time may be improved using a move-to-front heuristic or keeping it an ordered linked list.
		A linked list can be used to implement other data structures, such as a queue or a stack.

		Some advantages that a linked list has over an array are that you can quickly insert and delete items in a linked list.
		With a linked list, you simply rearrange those pointers that are affected by the change.
		Linked lists also allow you to have different-sized nodes in the list.

	Doubly Linked Lists
		Well, if you've mastered how to do ordinary linked lists, then it shouldn't be much of a leap to doubly linked lists.
		A doubly linked list is one where there are links from each node in both directions:
		You will notice that each node in the list has two pointers, one to the next node and one to the previous one - again, the ends of the list are defined by NULL pointers.

	Doubly-Linked and Circular Lists
		As a result, deleting the head of the linked list is easy: The new head is the successor of the old head.
		However, deleting the tail of a linked list is not so easy: The new tail is the predecessor of the original tail.
		A circular list is formed by making use of pointers which would otherwise be null: The last element of the list is made the predecessor of the first element; the first element, the successor of the last.

	[PATCH] Implement doubly-linked list
		As a side note, modprobe would _not_ strictly need doubly-linked lists, as the list is either tarversed one way or the other (inserting uses tail->head, while removing uses head->tail), thus reversing the list would be as good as using a doubly-linked list.
		I'll share my list as soon as it is in a shape suitable for discussion.
		Once I've managed a more complete listing of lists, I'll list what kind of lists are used, how many times, etc...

	Doubly Linked Free Storage
		The singly-linked free list used in the preceding section is kept sorted in order to facilitate the coalescing of adjacent free areas.
		Unfortunately since the free list must be kept sorted, every time an area is released it must be inserted into the list at the correct position.
		A secondary problem with the use of a singly-linked free list is that, given a pointer to an area, we cannot extract that area from the free list without traversing the list.

	[PATCH] Implement doubly-linked list
		You can do anything with a singly linked list you can with a doubly linked one, it's just slower in places.
		> - only doubly-linked lists for all: > -> a 4-byte impact at run-time per node > -> a small impact in code size (35 bytes) > - both types of lists: > -> no run-time impact, as nodes are the strict necessary size.
		Possibly having doubly linked list infrastructure is a good thing, but I want to identify more users and make sure they can't easily be rewritten to use our existing lists.

	Doubly linked list
		Before being inserted into the list the object pointer is wrapped in a TObjLink object which contains, besides the object pointer also a previous and next pointer.
		Storing an option is useful when one wants to change the behaviour of an object a little without having to create a complete new copy of the object.
		In idx it returns the position of the object in the list.

		If a job does not finish in its allotted time, it is moved to the "back" of the list (this is done by simply moving the current reference ahead in the list by one node).
		You are responsible for generating the class that represents a node in your list (more on this later).
		The end of the list is defined as the node immidiately preceeding the current node.
