A cellular automaton is defined as a system built from three components: a grid of cells, where each cell has a state and a neighborhood, and a transition rule where the state of a cell at time tt is computed as a function of the neighborhood states at time t−1t-1.

Conditions: The system is organized as a grid of cells.; Each cell carries a state and has an associated neighborhood.; The update rule uses the previous generation's neighborhood states.

The assigned exercise is to design a set of rules for how cell states change over time in a one-dimensional cellular automaton whose cells take only the values 0 and 1, which means choosing a function ff that maps each allowed neighborhood configuration at time t−1t-1 to a new cell state at time tt.

Conditions: The cellular automaton is one-dimensional.; Cell states are restricted to 0 and 1.; Rules must specify how cell states change over time.

The formula means that the state of a cell at the current time step tt is computed by applying a transition function ff to the states of its neighboring cells at the previous time step t−1t-1.

Conditions: tt represents the current discrete time step or generation index.; t−1t-1 represents the previous discrete time step.; ff is the transition rule mapping previous neighborhood states to the next cell state.

The simplest cell states mentioned are binary values, specifically 0 or 1, which can be interpreted as on/off, alive/dead, or black/white.

Conditions: The cell state is restricted to the simplest possible example.; The state set is binary.
