Since Python has dynamic lists and dictionaries, I suspect you won't
find any textbook focusing on linked-list or hashed lookup algorithms
using Python.
You can probably implement them

Sure, but I think you're timing the wrong thing here. You would only
allocate the lock relatively rarely - it's the overhead of *acquiring*
the lock that's the real problem.

It's not a full compare-and-swap but you could implement a

Very interesting idea. Will it work if accessed through ctypes?

Or does ctypes muck with the GIL in a way that would break this idea?

Anyone using Python for coding up genetic algorithms? If
so, would you share your favorite modules/libraries/tools?

I have done something in this direction. I will be happy to share my
experience. However, my code is not generic and needs many things to be
manually introduced. My GA is standard (selection by roulette wheel or
tournament, single point cross). Let me know if you are interested!

Not exactly but I am aware of Python code for nonlinear optimization
algorithms. Check the nlpy project at http://nlpy.sf.net It is

current trend in optimal control algorithms is to use grid-refinement
