Sorting ulong moves based on their score

[mvanthoor]

I know I won't make any competitive engine...

Mwhahaha ...

Go try and fool someone else. As soon as your engine is in the CCRL-list (or another rating list), you will want to make it stronger. If you're hitting roadblocks such as speed or bad structure, you'll either restart and write a new engine, or refactor it.

Just wait and see

Hahah yeh I guess you are right, I love optimizing things... Chess programming is a curse, I should have listened to those who said that one should never start writing one

Yes, I think it is good to change things like this early.
So when getting all possible moves I do something like this?

Code: Select all

ulong possibleMoves = new ulong[256];
int movesAdded = 0;

// if finding move....
possibleMoves[movesAdded] = newMove;
movesAdded++;

Sorry about all these newbie questions, I am not a very good C# programmer, I am so used to Python
And how do I loop through this list in Negamax? I don't want to loop over all possible moves that are 256 in this case, I only want to use the ones I added in the list.

Can’t you just put a dummy element just after the last valid element/move in the array. If 0 is not a legal move you don’t have to set anything, just check for 0 while looping.

Yup, that is what I did
