2019-08-23Improve PLRsearch yet againVratko Polak5-50/+166
Logic improvements for rls1908 and post-pylint fixes: + Reduce search time to 30 minutes. + Use average instead alternating loads. + Rework log/exp avg/stdev from two estimates. + Introduce and use pessimistic variance of dual trackers. + Introduce safe_exp to use when None does not skip code. + Use dot relative imports (instead of disabling pylint). + Complete docstrings for simpler functions. + Append docstrings to named tuples. + Somewhat unify docstrings related to the same arguments. + Slightly improve intentation. + State named tuples as rtype where used. + Add returns and rtype to __repr__ where missing. + Return what docstring say (or update them). + Explicit copying for vector and matrix values.

2019-05-10PLRsearch: Use stat trackers to shorten IntegratorVratko Polak3-401/+698
+ Extract several tracker classes and use them in Integrator. + Apply next_rate workarounds to focus more on critical region. + Rewrite stretch function, as the previous implementation was wrong. + Rework logging: ++ Use injected trace() function in Integrator. ++ Inject function that skips trace logging on default initialization. ++ Use the same multiprocessing-safe passing, but separate queue. + Set duration to 120m in Robot, but keep at 30m in Python. + Apply minor changes to make computations more reproducible: ++ Attempt to log everything needed by reproducibility in one line. ++ Log samples used, and make it settable as upper limit. ++ Use repr output in TRex scripts, to avoid rounding when copypasting. +- Numpy seems to be sharing PRNG between processes. +-- An edit to disable one thread is needed for full reproducibility. +-- Such an edit is prepared, but will not be merged anytime soon.

2019-01-29PLRsearch: Initial implementation and suitesVratko Polak4-0/+1079
Missing bits: - Add up-to-date .rst document (in child Change). - Prepare for releasing to PyPI.org (in child Change): -- Either copy dependencies from MLRsearch, or list in requirements. -- Perhaps move common dependencies to separate package for both search to depend on. -- All the other metadata stuff.
