# This file implements Brzozowski's parsing-with-derivatives (see:
# https://arxiv.org/abs/1604.04695) with fairly simple and
# straightforward Python code.  This implementation is naive and
# subject to exponential memory growth in the worst case; in practice,
# average complexity is closer to linear.  This version recalculates
# derivatives every time they are needed; memoization, the first and
# most obvious optimization, is not implemented.

"""
Takes a filename as its required argument.  The file should contain
names from a sample list, one name per line.  It creates a Markov
chain of one, two, and three-letter character sequences, including
octothorpe-anchored sequences for the starts of names.  It then
generates 'n' random names, each using the probabistic distribution of
three-letter character sequences, to make names that match the
patterns fed in the original.
