(15C/15C Limited Edition) Knight's Tour

[Archilog]

I owe to the truth that C.Ret has designed a better code for the HP-15C than mine, both much shorter and much faster. The only consolation I have is to know that his brilliant attempt was inspired by mine, which was quite laborious - but the first step counts, right?
Here it is, with his permission.



You will find the flowchart and some explanations in French there.

On the 15C Limited Edition, the chessboard run lasts just under 12 seconds 9 tenths.
I will edit this message for the result of the vintage 15C: it is still calculating.

EDIT: On the vintage HP-15C, Knight's Tour is completed in less than 33 minutes 06 seconds 79 hundredth.
So the ratio in this program is 164,33 (Limited Edition version is 164 times faster than vintage version).
