Otherwise, the algorithm (1) checks whether c itself is a valid solution, and if so reports it. “On 33-hole solitaire positions with rotational symmetry”, 2012. “Solving triangular peg solitaire”, Journal of Integer Sequences, 11, 2008. “Triangular peg solitaire unlimited”, Games and Puzzles Journal, 36, 2004. “Peg Solitaire”, in Knots and Borromean Rings, Rep-Tiles and Eight Queens, Cambridge Univ.

The common mechanics is that a selected peg is capable to jump any directly adjacent single neighbour in straight direction onto a free position. “Purging pegs properly”, in Winning Ways for Your Mathematical Plays, 2nd ed., Vol. The mind bending puzzle of Peg Solitaire is well-known using different board shapes and different amount of holes for placing the pegs. The Ins and Outs of Peg Solitaire, Oxford Univ. If you enjoyed this article, please consider following me on twitter.Beasley, J. Peg solitaire, Solo Noble or simply Solitaire is a board game for one player involving movement of pegs on a board with holes. ("Completed in " + (System.currentTimeMillis() - time) + " ms.") start recursively search for the initial board from the goal (reverse direction!) fill in the global moves variable that is used by the solver randomize the order of the moves (this highly influences the resulting runtime) Private static void printBoard(long board)

Input files and source code are found in the attachment. Private static final long moves = new long A program that solves the peg solitaire game finding the best possible solution. Private static final long VALID_BOARD_CELLS = 124141734710812L with vertical) and 4×4 Peg Solitaire (2-D)(Fig. Private static final long INITIAL_BOARD = 124141717933596L logic programming invariably involves predicates with fixed arities. Private static final long GOAL_BOARD = 16777216L Private static final ArrayList solution = new ArrayList() Private static final HashSet seenBoards = new HashSet() The following is 52 lines of code according to IntelliJ LoC metric. Update: In the following you’ll find the Java version, but the reddit user leonardo_m has also translated the code to C++! which move makes “more sense” for a given board. The branch that the algorithm follows might not include a solution, but it still is searched in its entirety.Īn idea to reduce the fluctuation would be to use heuristics and to rank the moves depending on the board, i.e. The program always checks the moves in the same order when looking at any given boards and sometimes this (initially determined) order is “unlucky”. Interestingly the run time highly fluctuates, depending on the ordering of the possible moves. In general a gigabyte of ram, used to remember the known boards, should be enough to allow for a solution to be found. Not doing so means that my computer is still working on a solution since 24 hours (however it is using almost no ram). As mentioned before, the leftmost, bottommost element is considered as the 00 element of the array. Sample I/O (Input/Output) Here is a sample I/O for Milestone submission. Remembering the boards that we have already seen (and not rechecking them unnecessarily) means that a solution is found in a very reasonable time (usually a few seconds). You only need to write code in the main method. With this particular algorithm it is no different. There is often a tradeoff with algorithms when it comes to memory usage and run time. You can find more details on this in the comment header of the program below. The really interesting part is that the algorithm is optimized by reverting the search direction. Checking of possible moves and applying them can be done by using simple bit operations. However there are some bits that are not valid and never used, i.e. The first 49 bits (7 x 7) of the long represent the board.
The idea is as following: Since there exists 33 slots on the board, it can not be represented by using an integer (32 bits), but we can use a long (64 bits). The implementation is highly optimized and uses bit operators to efficiently find a solution.
