pyphi.core.repertoire_algebra

Stateless repertoire computation over System.

Layer 2 of the kernel. Functions take a System as the first argument; results are memoized via a per-instance decorator that purges when the System is garbage-collected.

Threading

The kernel cache is the thread-safe pyphi.cache.ContentCache (eviction and refcount bookkeeping locked; the hot read path lock-free) — see pyphi.cache.

Functions

cache_info()	Return per-function cache size.
cause_effect_info(cs, mechanism, purview, ...)	Cause-effect information — minimum of cause and effect information.
cause_info(cs, mechanism, purview, **kwargs)	Cause information — distance between cause repertoire and unconstrained.
cause_repertoire(cs, mechanism, purview, ...)	Cause repertoire πc(z | m) of a mechanism over a purview.
clear_caches([cs])	Clear cache entries.
effect_info(cs, mechanism, purview, **kwargs)	Effect information — distance between effect repertoire and unconstrained.
effect_repertoire(cs, mechanism, purview[, ...])	Effect repertoire πe(z | m) of a mechanism over a purview.
expand_cause_repertoire(cs, repertoire_array, *)
expand_effect_repertoire(cs, repertoire_array, *)
