Overview
A TransitionMatrix is an object for storing and selecting transitions in a Markov::Chain.

-
.new(pull : JSON::PullParser)
Makes it possible to use
#to_jsonand#from_json(see Crystal docs) -
.new
Creates a new empty
TransitionMatrix.
Instance Method Summary
-
#add(link : LinkType)
Adds item to
TransitionMatrix -
#probabilities : Hash(LinkType, Float32)
Returns decimal probability of each transition in the matrix
-
#probable_transition : LinkType
Chooses a random, probable transition from the transitions in the matrix.
-
#sum : Int32
Returns sum of all values (occurrences) in the matrix
