, there is often a conversion parameter from order to chaos. For example, the dripping water on the tap in our daily life shows different and stable complex dynamic behaviors with the change of water flow speed, such as one-point, two-point, or multiple-point periods, and even chaos and extreme disorder, apparently, the flow speed here. Or water pressure is the state parameter of this nonlinear system. Langton defines a parameter for the conversion function, so as to compare the function space p

Using a metaphor from a daughter's Country: A metacell is a mother. She has a daughter, which can have a daughter, be single, or be a descendant of mantang, it is critical that a daughter of the same generation does not need to be of the same data type.
The iscell () function mainly makes a judgment,

How to Use Cython to accelerate Python code and cythonpython
Introduction
Generally, writing a loop (especially multiple loops) in Python is very slow. In the article http://www.bkjia.com/article/132.167.htm, our new function update_state of the metacell automatically uses two repeated loops. Therefore, we try to use Cython to reconstruct this method.
