Perft(14) Weekly Status Reports for 2015

Hi,
I've heard that you don't use Bit-boards for your move generation. What exactly is the reason behind this?

I've heard that you don't use Bit-boards for your move generation. What exactly is the reason behind this?

Symbolic is an ANSI C++ bitboard program throughout. This is because bitboards make programming conceptually easier and are also fairly efficient on 64 bit machines. Symbolic is being used for the project because it has a well established legacy for correctness performing perft() operations.

Oscar is an ANSI C mailbox (piece set) program under development for perft() and other tasks; it does not use bitboards. Instead, it is optimized for 32 bit architectures as seen with video GPUs via the OpenCL environment. It has helped with the project and will take over most of the effort soon.

Symbolic is private; Oscar will be released under an open source license.

Here's Oscar's output for the aforementioned position:
