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.
Deduction from a single number. Red and blue patterns imply each other. When numbers 1, 2 or 3 get its connections, one can fill remaining cells The other way around applies: numbers 1, 2 or 3 with that amount unfilled cells and other cells avoiding the number specify the remaining cells points to the number.
Word problem for linear bounded automata [25]; Word problem for quasi-realtime automata [26]; Emptiness problem for a nondeterministic two-way finite state automaton [27] [28] ...
The Goat Puzzle (also known as The Infamous Goat Puzzle, The Infamous Goat, The Wretched Goat, The Goat of Lochmarne, or simply The Goat) is a puzzle featured in Revolution Software's 1996 point and click adventure game Broken Sword: The Shadow of the Templars. In the puzzle, protagonist George Stobbart must gain access to an underground dig ...
Groups of puzzles in a puzzle hunt are often connected by a metapuzzle, which is a puzzle based on combining or comparing the answers of other ("feeder") puzzles. For some metapuzzles (sometimes called "shell" metapuzzles), the answers to the feeder puzzles must be incorporated into a puzzle structure that is separately provided to solvers; for ...
Bag is played on a rectangular grid, usually of dashed lines, in which numbers appear in some of the cells. The object is to draw a single, continuous loop along the lines of the grid that contains all the numbers on the grid. Each number indicates the total number of cells visible in any orthogonal directi
Mathematical puzzles require mathematics to solve them. Logic puzzles are a common type of mathematical puzzle. Conway's Game of Life and fractals, as two examples, may also be considered mathematical puzzles even though the solver interacts with them only at the beginning by providing a set of initial conditions. After these conditions are set ...
Environmental Go, also called Coupon Go, [10] invented by Elwyn Berlekamp, adds an element of mathematical precision to the game by compelling players to make quantitative decisions. [11] In lieu of playing a stone, a player may take the highest remaining card from a pack of cards valued in steps of 1 ⁄ 2 from 1 ⁄ 2 to 20: the player's ...
