Hello ShootMe

I discovered a counterexample to MinimalKlondike finding the fewest possible moves for any deal, including unsolvable deals. The link is https://greenfelt.net/klondike?game=2095819838.

MinimalKlondike finished the search with a score of 10 in 54 moves. The "high scores" button shows a score of 10 in 53 moves. This may be a trivial counterexample but I thought you might be interested. It is my understanding that MinimalKlondike performs an exhaustive search of all possible moves. In this particular case, a move was saved by not playing the 4-hearts onto the 5-clubs.

Thanks to MinimalKlondike, the skills that I have acquired improve daily and the joy that I experience playing Klondike exceeds my expectations.

thanks for sharing this solution , but I hava some questions.

1.How to make sure this is the minimum solution?

2.It's hard for me to understand the solve process , Can share your thinking?

thanks.

Hello ShootMe

Would you please run this command line on MinimalKlondike with a sufficiently large value for -S option to generate a solution.

klondike -S 500000000 1492773577

The above command line ran on my laptop for several hours without a solution while using the maximum available memory on my 16GB system.

This deal is solvable as evidenced at https://greenfelt.net/klondike?game=1492773577.

Please post the solution and the value used for -S option.

Thanks for your assistance.

ShootMe stated in a previous thread:
"Go ahead and redownload the zip. I added a way to just specify a seed from GreenFelt

Klondike.exe Seed#

Will solve that given seed. You can also specify -D 3 if you want to solve the draw 3 variant"

Wow...pure genius...but you just opened the door to cheating on GreenFelt on a massive scale!

How were you able to retrieve the starting positions of the full 52 card deal? I previously tried inspecting the html code to retrieve the deal order without any success. Do you have access to some sophisticated html debugging software? To my knowledge, nobody who uses the GreenFelt site has ever succeeded in breaking the html code to retrieve the deal order.

this is my klondike command : Klondike.exe 062122133041014042081034084111053124132083091113022071074023082033131021061104043064092054134

this is my cards : 6D,??,??,??,??,??,??,
QD,??,??,??,??,??,??,
KH,??,??,??,??,
4C,??,??,??,
AS,??,??,
4D,??,
8C,

and this is deck(drawing cards) : 3S,8S,JC,5H,QS,KD,8H,9C,JH,2D,7C,7S,2H,8D,3H,KC,2C,6C,10S,4H,6S,9D,5S,KS

when I run command witout initial move. it gives this output : Klondike.exe 062122133041014042081034084111053124132083091113022071074023082033131021061104043064092054134

any help appreciated.

Hello ShootMe

MinimalKlondike is amazing on GreenFelt. As I told you previously, I have used it hundreds of times to only attempt to solve deals that are actually solvable.

My understanding is that the your code will often require a lengthy time to find the minimal solution. It would be a great timesaver if, prior to searching for the minimal solution, the code outputs a message informing the user that the deal is solvable.

Thanks for your assistance.
