 The data model in [`cas-core`](/cas-core) abstracts common characteristics of  cellular automata, forming a fundamental structure to simulate any cellular automaton. The set diagram below shows the composition between the elements of the data model, suppressing cardinality.

 [`Time`](cas-core/src/main/java/com/ghjansen/cas/core/physics/Time.java) increases its counters during a simulation in a mathematical ratio equivalent to the product of the limits of the relative counters multiplied by the limit of the absolute counter, minus one. This formula is shown in the image below, where `a` represents the absolute counter,`d` represents the amount of relative counters (or amount of dimensions), `ri` represents a relative counter `i` and `lim` is the function that obtains the limit of each counter.

 ### Space
 The [`Space`](cas-core/src/main/java/com/ghjansen/cas/core/physics/Space.java) class is a dynamic array responsible for keeping all [`Cell`](cas-core/src/main/java/com/ghjansen/cas/core/physics/Cell.java)s from the initial condition defined for the simulation (`initial` attribute), the history of the iterations already processed (`history` attribute), the last iteration processed (`last` attribute) and the iteration that is being processed (`current` attribute). The `initial`, `last` and `current` attributes are lists of generic type in order to allow multidimensional structures, whereas the `history` attribute is a list of lists, since `history` stores copies of `current`. The image below shows a representation of the attributes `initial` (A), `history` (B), `last` (C) and `current` (D) through the computation of elementary rule 110.

 ### CellularAutomaton
 The [`CellularAutomaton`](cas-core/src/main/java/com/ghjansen/cas/core/ca/CellularAutomaton.java) class is the conceptual representation of the cellular automaton used in the simulation. The logic of this class uses other classes like [`Rule`](cas-core/src/main/java/com/ghjansen/cas/core/ca/Rule.java), [`Transition`](cas-core/src/main/java/com/ghjansen/cas/core/ca/Transition.java), [`Combination`](cas-core/src/main/java/com/ghjansen/cas/core/ca/Combination.java) and [`State`](cas-core/src/main/java/com/ghjansen/cas/core/ca/State.java).
