Peg solitaire game traingle9/7/2023 ![]() Now the slowest solution to find takes 1. % fastest: 0.007 seconds (6) slowest: 1.558 seconds (12)ĮDIT: I improved the performance by calculating the possible jumps first instead of picking 2 pins and then checking if they are are a valid jump. The game is called solitaire (Latin solus alone. In the end one peg should be left in the centre hole. You have to remove the pegs one after the other by jumping horizontally or vertically over one. A game board with 33 holes in cross form is given. Neighbors_(Row, Row, Row, From, To, Middle):- Peg solitaire is an old board game for one player. Neighbors_(FRow, TRow, MRow, From, To, Middle):. Neighbors_(FRow, TRow, MRow, From, To, Middle), Put_assoc(To, UAssoc1, To, UpdatedAssoc). Update(Assoc, From, Middle, To, UpdatedAssoc):. Update(Assoc, From, Middle, To, UpdatedAssoc), Sometimes it solves it almost immediately even :) :- use_module(library(assoc)). SWI-prolog and I decided to solve it with assocs.Īfter creating a random puzzle, it solves it in reasonable time. Spoilers: the first solution I found is, ,, ,, ,, ,, ,, , ] using the peg index notation in the OP. Scanl(checkers_move, CoordMoves, Tinit, Ts), Swap_triangle(Mid, Ta, 1, Tb, 0), % remove victim peg Tri_neighbor(Mid, End, Dir), % locate landing spot Tri_neighbor(Start, Mid, Dir), % locate victim peg ![]() Swap_triangle(Start, T1, 1, Ta, 0),% take jumping peg % => easy to compute neighbors in the 6 directions % implement peg indexing by (I,J) position in triangular lists Var(J) % if index is known in advance, do deterministic search % select/4 except it exposes the index of the replacement Wish there was a built-in for doing swap_list below (or am I missing it?). ![]() Swi-Prolog, no libraries, simple output format since none was specified. ![]() Please comment with suggestions for future challenges or improvements to the format. Can you do it in Logtalk, CHR, Mercury, Picat, Curry, miniKanren, ASP or something else?Ĭhallenge 1 - Stack Based Calculator Challenge 2 - General Fizzbuzz Challenge 3 - Wolf, Goat and Cabbage Problem Challenge 4 - Luhn Algorithm Challenge 5 - Sum to 100 Challenge 6 - 15 Puzzle Solver Challenge 7 - 15 Puzzle Game Implementation Challenge 8 - Hidato Challenge 9 - Trapping Rain Water Challenge 10 - Maze generation Challenge 11 - The Game of Pig Challenge 12 - Conway's Game of Life Challenge 13 - Rock paper scissors Challenge 14 - Monty Hall problem Challenge 15 - Tic-tac-toe Challenge 16 - Longest common prefix Challenge 17 - Merge sort Challenge 18 - Closest pair problem Challenge 19 - Topological sort Challenge 20 - Poker hand analyser Challenge 21 - Greed Challenge 22 - Nim game Challenge 23 - Base64 encoding and decoding Challenge 24 - Sum and Product Puzzle Solutions in non-Prolog logic programming languages are most welcome. Your task is to display a sequence of moves (jumps) starting from the position with pegs (tees?) in all holes except hole 1 and ending with a position with only one remaining peg. Peg #1 is the top centre through to the bottom row which are pegs 11 through to 15. The fewer tees left, the higher the IQ score. This puzzle is typically seen at Cracker Barrel (a USA sales store) where one tee is missing and the remaining tees jump over each other (with removal of the jumped tee, like checkers) until one tee is left.

I spent a bit of time on this step as I thought it was a fun way to do it. ![]() In the build video, I’ll walk you through laying out the hole locations by hand. They are very inexpensive and come in an assortment of colors. You need to cut the piece into an equilateral triangle, then drill some holes in it to fit whatever material you want to use for the pegs. You can glue up some smaller pieces, or use just about any board you have on hand. This project is a good one to use up some scraps. If you’ve played it, you’ll know how fun it is, and if you haven’t played it you need to. You might be familiar with it from a truck stop, or certain restaurant chain. This game has been around for a long time, and I’ve been playing it myself since I was a little kid. In this weird year we call 2020, who couldn’t use a game to play to help pass the time. ![]()
