Detailed Description

template<typename... Rules>
class Aleph::CA::Composite_Rule< Rules >

Sequential composition of one or more rules.

Composite_Rule<R1, R2, ..., Rn> applies R1 first, then R2 on the resulting state, and so on. The neighbour view passed to every stage is the same (read at the start of the step), which is the standard semantics for layered totalistic rules.

Template Parameters

Rules

rule types applied from left to right.
