Real-life connections
Name one real-life example
Chemical reaction or shell pigmentation
Name an interesting creature or behavior.
R-pentomino, Gemini, eater, glider, undecidability, etc.
What states can the cell be in?
Alive or dead
What is the decimal representation of 110?
6
Describe TTL protocol for logic.
Voltage high is 1 low is 0.
Name another real-life example
Chemical reaction or shell pigmentation
Describe the rules.
Depends on the number of alive cells of the nearest neighbors.
When plotting the results for rule 30 that shows a pyramid-like structure, what does the vertical axis represent?
Generations of evolution.
What is the binary representation of 10?
1010
What does XOR gate do?
One returns true if exactly one input is true.
Describe the pattern of the chemical reaction
Concentric circles
Describe the creature that self-replicates
Deletes the previous copy after a new copy is created. Has a very long tape that contains the instructions. Moves one big step after millions of generations.
If you want to have different output plots of the results, what can you change?
The rule or the initial condition.
What is 110+011
1001
What does NAND gate do?
Outputs False only if both inputs are True.
What is the difference between real shell patterns and the cellular automaton model?
Real cells can have long-range neural modulation.
Describe two interesting creatures in the game of life (not mentioned before).
R-pentomino, Gemini, eater, glider, etc.
What kind of behaviors have been demonstrated with these cellular automata?
What is 1101-0111?
110
What gate constitutes a universal set?
NAND.
What will happen for the chemical reaction if the division factor k2 for the cells with value 255 goes to 8 (the maximum)
The chemical reaction dies and all cells end up having value 1 very quickly
What is the shape of the five cell structure that leads to the longest non-repeating evolution
What is 101*101?
11001
How many two input binary logic operations are there in total? Not just the ones with good names.
16.
