ranks wont be changed 🤷

Much more than size 50 !! I test with size 5 - 80. When size are more than 70, all (x,y) work in almost 1 minute... I just say 5 to 50, your code run with all (x,y) in less than 5 minutes, and some program who use backtracking can't solve only one case, for example, size = 7, x = 0, y=1, in these 5 minutes...
Size = 5, seem minimum, I think it's because knight's move are 'long' and a little bit strange, in "L"...
When you talk about heuristic, are min/max algorithms, are an heuristic method ?
If you are so good in playing chess that you are in coding, it's better I never play against you in chess game ( I'm a very little beginner for this fabulous gama)

Thanks! I glad you like this solution!
It is using "Intelligence" (an Heuristic) vs "Brute Force" (Backtracking)
It is nice to know that the algoritm also work fine with nxn form 5.. to 50!! Thats is really crazy and with a runtime of less than 5 min... that blob my mind! :)

Thanks for the fedback an the extra info!
I hope more chess and coders enthusisats will enjoy it!
Regards!

Congratulation !!! Very good job, I try your code, the fastest code I see here : size from 5 to 50, x from 0 to size, y from 0 to size ( each value test for all, with 3 for loop ... 100 % good result, in less than 5 minutes !!!! I 'll studie your code, because mine, is very long, rought draft and don't send always 100 % good result ^^

There's no difference.

Already raised as an issue.

No clue what you wrote, I didn't read it

Thanks! Sorry for the issues...

yep, seems all good.

Approved again ;-)

I've approved the new kumite twice, is that a fix of the issue above?

Fixed Three Issues:

• the random tests can generate white king and queen at the same position
• expected and actual are swapped in all the tests (random, fixed and sample tests).

Fixed the issue:

• do NEVER put your reference solution in a public place. Especially, in the preloaded part..

I have put the validator class in a private inner class in the test case class.
I delete the validator from the preloaded part

Hi pablo,

Could you take a look at my messages above and address the different issues, please?

Cheers,
