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})} .
Boggle is a word game introduced in 1972 and in which players try to find as many words as they can from a grid of lettered dice, within a set time limit. It was invented by Allan Turoff [ 1 ] and originally distributed by Parker Brothers .
Age range 6+ Connect Four (also known as Connect 4 , Four Up , Plot Four , Find Four , Captain's Mistress , Four in a Row , Drop Four , and Gravitrips in the Soviet Union ) is a game in which the players choose a color and then take turns dropping colored tokens into a six-row, seven-column vertically suspended grid.

Robot in a wooden maze. A maze-solving algorithm is an automated method for solving a maze.The random mouse, wall follower, Pledge, and Trémaux's algorithms are designed to be used inside the maze by a traveler with no prior knowledge of the maze, whereas the dead-end filling and shortest path algorithms are designed to be used by a person or computer program that can see the whole maze at once.
The Indiana vs. Notre Dame matchup in the first round of the College Football Playoff is the most expensive ticket on StubHub, but it's Tennessee vs. Ohio State that's selling the fastest.
