MarkovChain

Undocumented in source.

Constructors

this this(): Undocumented in source.
this this(size_t[] sizes): Constructs a markov chain with empty states of the given sizes.
this this(State!T[] states): Constructs a markov chain using a list of existing states.

feed void feed(T[] first, T follow): Trains the markov chain with a specific token sequence.
generate T generate()
Nullable!(Unqual!T) generate(): Returns a token generated from the internal set of states, based on the tokens previously generated. If no token can be produced, a random one is returned.
generate Unqual!T[] generate(size_t length): Ditto, but produces an array of token with the given length.
generate size_t generate(size_t length, Unqual!T[] output): Ditto, but the array is given as an out-parameter.
push void push(T follow): Pushes a token to the markov chain's history buffer.
seed void seed(T[] seed): Pushes tokens to the markov chain's history buffer, seeding it for subsequent calls to select() or generate().
select T select()
Nullable!(Unqual!T) select(): Returns a token generated from the internal set of states, based on the tokens previously generated. If no token can be produced, null is returned.
train void train(T[] input): Trains the markov chain from a sequence of input tokens.

empty bool empty [@property getter]: Checks if all of the markov chain's states are empty.
length size_t length [@property getter]: Returns the number of states used by the markov chain.
lengths size_t[] lengths [@property getter]: Returns the lengths of the markov chain's states in an unknown order.
random T random [@property getter]
Nullable!(Unqual!T) random [@property getter]: Returns a randomly selected token from a randomly selected state.
rehash void rehash [@property getter]: Rehashes the associative arrays used in the markov chain's states.
reset void reset [@property getter]: Resets the markov chain's history buffer to an empty state.
sizes size_t[] sizes [@property getter]: Returns the sizes of the markov chain's states in an unknown order.
states State!T[] states [@property getter]: Returns an array representing the markov chain's internal set of states.
