here's the last draft doc that reached github:
# for designing an interface of system simulation
# a simple system where some property is a function of time.
# goal 1: user has access to a state containing a number, and can produce
# another state based on a time change from the first
# number = constant * time
# goal 2: model user in a way that can be simulated, to mutate
# the constant. the simulation can be simply a uniform
# distribution of chance of change.
# goal 3: simulate a single timeline, letting the user move along it
arbitrarily,
# using the user's model of behavior to predict state.
# goal 4: simulate multiple timelines, with an interface as to whether to
bind
# actions to one or spawn a new one. be nice to have that be a
float
# probability of binding.
# note: user and sim could share the same interface for predicting state
given environment and time
# note: user and number could both be equal peers
# design choices/ideas:
# - update functions take new time, not time change. expected to be
more refactorable if need.
