A class 1 computation description according to the reading selection is “Class one. Enter a constant state.” I think there are a few examples of this, one of the first examples that popped into my head of something entering a constant state, is on television shows when someone is in the hospital sick. When the person is living the monitor has a line that has curves and spikes to the persons body, when they finally die the line goes into a constant straight line like a class 1 computation. The next computation is a class 2 “Generate a repetitive or nested pattern.”. The first thing that comes to mind is Sol Lewitt, and his instruction sets. His instruction sets are very basic and follow a general pattern. Like the line drawing, continues a specific pattern throughout the entire wall. Class 3 computation “Produce messy, random-looking crud.” one thing comes to mind is a paint splatter art. Throwing random paint and blobs that occur anywhere and looks extremely random. I can not think of any class 4 computations “Produce gnarly, interacting, non repeating patterns”.

One computation that is extremely feasible is what I listed for my class 3 computation, paint splatter art. The input is extremely easy to do, throwing paint onto a surface; but the output is extremely random. Even if you try to throw the paint a specific way, the paint will move based on the air movement or strength on how you threw it, creating a random output. The input is completely feasible and simple, but the output of the paint on the canvas or surface is completely random and unpredictable.

Class 3 and Class 4 computations seem very similar, what I have come to notice the difference between the two are interaction. While both are extremely intricate the main difference is interaction. They are non repeating, and from what I understand a Class 4 is more organized and more interactive with each other. Class 4 images are a different like twisting tree roots or large ocean waves. The distinction is still very minimal. I do not understand the differences completely but I can understand smaller variations between the two.

Continuous-valued Cellular Automata differs from the Game of Life because there is a continuous amount of integers where the game of life will eventually run into a constant state of equal librium. There is no restriction on the on the values of the cells either, because there is a continuous set of locations. Those are the main differences between Continuous-valued Cellular Automata and the Game of Life.
