In computer science, jump point search (JPS) is an optimization to the A* search algorithm for uniform-cost grids. It reduces symmetries in the search procedure by means of graph pruning, [1] eliminating certain nodes in the grid based on assumptions that can be made about the current node's neighbors, as long as certain conditions relating to the grid are satisfied.
The advantage is that all optimizations of grid A* like jump point search will apply. A visibility graph with all the grid points can be searched with A* for the optimal solution in 2D space. However, the performance is problematic since the number of edges in a graph with V {\displaystyle V} vertices is O ( V 2 ) {\displaystyle O(V^{2})} .
Kid Grid is a grid capture game which borrows heavily from the 1981 arcade video game Amidar. [ 2 ] [ 3 ] Written by Arti Haroutunian for Atari 8-bit computers , it was published by Tronix in 1982. [ 1 ]
The number of Invention Points required to enter the Time Machine gradually increases over time. Once inside the Time Machine Mission Control, the user has to get past the Wheel of Invention in order to acquire a Time Key and enter the Time Machine itself, though Polly has apparently reprogrammed the Wheel so it's not just a quiz, but rather a ...

At most points can be placed, because + points in a grid would include a row of three or more points, by the pigeonhole principle. Although the problem can be solved with 2 n {\displaystyle 2n} points for every n {\displaystyle n} up to 46 {\displaystyle 46} , it is conjectured that fewer than 2 n {\displaystyle 2n} points can be placed in ...
An alphanumeric grid (also known as atlas grid [1]) is a simple coordinate system on a grid in which each cell is identified by a combination of a letter and a number. [ 2 ] An advantage over numeric coordinates such as easting and northing , which use two numbers instead of a number and a letter to refer to a grid cell, is that there can be no ...
JumpStart Typing is a personal computer game intended to teach typing skills to kids aged seven to ten. The game reuses the cast of JumpStart Adventures 3rd Grade: Mystery Mountain . The game is set at Sparks Stadium, where keyboarding Olympics take place between the Sparks Team and the Galaxy Gladiators.
