I had to change the algorithm with java. Instead of the standard rook and bishop move generation, I split
|
|
them up into direction and then get each direction individually. This is slower but stops me needing a 54x4096 and
|
|
64x512 array. This is a problem because ulongs are not directly supported in java.
|

You have two choices
|
|
1. convert all the constants to minus, if they are over the max signed long value, and risk a lot of bugs and testing that way.
|
|
2. convert all the constants to BigIntegers like this:
|
|
static final BigInteger MAX_ULONG = new BigInteger("18446744073709551615");
|
|
This means replacing all values with this type in all constants. You also need to use OOP for everything.
|
|
This:
|
|
BigInteger bitboard = bitboard1 & bitboard2;
|
|
Turns into:
|
|
BigInteger bitboard = bitboard1.and(bitboard2);
|
|
|
|
I chose the second approach and tried converting everything over to this. I created so many bugs that I couldn't fix and
|
|
gave up in the end.
