Comment(by ylchapuy):
My 2 cents:
* the complexity is 'n * 2**m' (instead of 'm * 2**n'):
{{{
for x in X: <-- 2^m
for output_bit in output_bits: <-- n
}}}
* typos:
* line 866: evaluate instead of evaulate
* line 840: endianness instead of endianess
* maybe add an exception if xi or yi has wrong size
* maybe (but as you like) construct x's on the fly:
{{{
for e in xrange(2**m):
x = self.to_bits(e)
}}}
otherwise seems good to me.
