Matrix

public typealias Matrix<T> = [T : Vector<T>]

Undocumented

  • All the unique states present in the current matrix. Even though it’s a from or to state only, it will be counted as a unique state.

    Complexity

    O(n log n), where n is the matrix’s size

    Declaration

    Swift

    public var uniqueStates: [Key] { get }

  • Given a current state, this method returns the probabilities of the next state.

    Complexity

    O(1), regardless the matrix’s size.

    Declaration

    Swift

    public func probabilities(given: Key) -> Vector<Key>

    Parameters

    given

    The current state.

    Return Value

    A dictionary of the probabilities, where the states are the keys and the values are the probability from the current state.

  • Given a current state, this method returns the next state, based on an input criteria.

    Complexity

    O(n), where n is the length of the possible transitions for the given states.

    Declaration

    Swift

    public func next(given: Key, process: DecisionProcess = .predict) -> Key?

    Parameters

    given

    The current state
    process

    The decision process to calculate the next state.

    Return Value

    The calculated next state.

  • A pretty printed representation of the matrix
