Detailed Description

template<typename Cell_Rule>
class Aleph::CA::Cell_Rule_As_Block_Rule< Cell_Rule >

Adapt a regular cell rule (with empty neighborhood) to a block rule.

Wraps a RuleLike cell rule whose transition depends only on its own state and applies it independently to every cell of the block. This is the trivial bridge that makes simple per-cell updates available to any Block_Rule consumer (e.g. Margolus_Update).

The wrapped rule must be invocable as cell_rule(state) returning the next state, mirroring an "outer 0-arg" (no neighbours) form.

Template Parameters

Cell_Rule

wrapped cell-rule type.
