CMWC is proven to be a valid method and it passes diehard tests. It was written by prof. George Marsiglia (he developed xorshift too - included

Would be great if you wanted to contribute an implementation of CMWC
to std.random.

Thanks,

That's something I could undertake confidently.

Writing both an actual engine, and creating aliases for pre-optimized
schemes.

I'd just have to wait to finish my current development (I don't know how
to have parallel forks).

That would be awesome (both RNG and getting fluent with parallel forks).

I gave it a shot, but I just couldn't find enough documentation on CMWC to write a correctly parametrizable engine. I honestly don't have much to go by other than wikipedia's example. I could force the implementation, but I'd have zero faith in it's reliability.

That said, I don't think it would be a bad idea to add a Lagged Fibonacci generator first. The generator already exists in boost, and is much more documented. The actual development would just require a port.

I'll try to get *that* done, but for CMWC, I'm out. Sorry.

The bright side is I learned to parallel fork :D
