Is there a limited number of models? The model should stay decoupled from the state as they are totally distinct
so general-fn[model old-state] -> new-state then either you (if you know the model) or the user if they can choose any model should define a partial fn partial specific-model-fn general-fn[model] so that it is always clear which model is being used to idiot proof the situation, which was your worry the partial fn can then be used with all the clojure goodies such as iteration and reduction as jony hudsun has pointed out all I am adding to the debate is suggesting having a named partial fn named after the model you are using, for clarity On Sunday, September 14, 2014 3:28:10 AM UTC+1, RJ Nowling wrote: > > Hi all, > > I'm new to Clojure and implementing a Markov Model as part of a larger > project.
