  2. Pathfinding - Wikipedia

    en.wikipedia.org/wiki/Pathfinding

    Two primary problems of pathfinding are (1) to find a path between two nodes in a graph; and (2) the shortest path problem—to find the optimal shortest path. Basic algorithms such as breadth-first and depth-first search address the first problem by exhausting all possibilities; starting from the given node, they iterate over all potential ...

  3. A* search algorithm - Wikipedia

    en.wikipedia.org/wiki/A*_search_algorithm

    A* was originally designed for finding least-cost paths when the cost of a path is the sum of its costs, but it has been shown that A* can be used to find optimal paths for any problem satisfying the conditions of a cost algebra. [8]

  4. PATH (variable) - Wikipedia

    en.wikipedia.org/wiki/PATH_(variable)

    On DOS, OS/2, and Windows operating systems, the %PATH% variable is specified as a list of one or more directory names separated by semicolon (;) characters. [5]The Windows system directory (typically C:\WINDOWS\system32) is typically the first directory in the path, followed by many (but not all) of the directories for installed software packages.

  5. Longest path problem - Wikipedia

    en.wikipedia.org/wiki/Longest_path_problem

    In graph theory and theoretical computer science, the longest path problem is the problem of finding a simple path of maximum length in a given graph.A path is called simple if it does not have any repeated vertices; the length of a path may either be measured by its number of edges, or (in weighted graphs) by the sum of the weights of its edges.

  6. Path Finder - Wikipedia

    en.wikipedia.org/wiki/Path_Finder

    Path Finder (originally SNAX) is a Macintosh file browser developed by Cocoatech. [1] [2] First released in 2001 simultaneously with the public release of Mac OS X 10.0 (Cheetah), [3] it replicates or integrates most of the features of the Finder, but introduces additional functionality similar to that found in the Windows File Explorer, the defunct Norton Commander, and other third-party file ...

  7. Path - Wikipedia

    en.wikipedia.org/wiki/Path

    Path (computing), in file systems, the human-readable address of a resource PATH (variable), in computing, a way to specify a list of directories containing executable programs; Path (graph theory), a sequence of edges of a graph st-connectivity problem, sometimes known as the "path problem" Path (topology), a continuous function

  8. Disjoint-set data structure - Wikipedia

    en.wikipedia.org/wiki/Disjoint-set_data_structure

    One family of algorithms, known as path compression, makes every node between the query node and the root point to the root. Path compression can be implemented using a simple recursion as follows: function Find(x) is if x.parent ≠ x then x.parent := Find(x.parent) return x.parent else return x end if end function

  9. Path (computing) - Wikipedia

    en.wikipedia.org/wiki/Path_(computing)

    A path (or filepath, file path, pathname, or similar) is a string of characters used to uniquely identify a location in a directory structure.It is composed by following the directory tree hierarchy in which components, separated by a delimiting character, represent each directory.
