Hi all. First. For those who remember, I posted an individual-based model in this group some time ago (eden.clj), and got some very helpful replies on where I misunderstood clojure and did things the hard way. I wanted to report that that model by now is written purely as nonblocking agents, and is happily burning cpu cycles as it simulates the evolution of our immune system :). thanks for that!
Second. I am updating an older model on Chlamydia prevalence in a dynamic sexual contact network, and implemented it in clojure (http:// clojure.googlegroups.com/web/chlam-clean.clj), based on the model in this paper (http://aje.oxfordjournals.org/cgi/content/abstract/ 144/3/306). It isn't fully equivalent to the model in the paper yet (for some reason, Chlamydia keeps going extinct), but that is something I will puzzle over myself. I am however, still somewhat fuzzy on what a good way is to get the model concurrent. I tried replacing (doseq [e [retire-host slowdown-host infect-hosts naturalrecovery-host pair-host breakup-host] i world] (e i)))) with (doseq [e [retire-host slowdown-host infect-hosts naturalrecovery-host pair-host breakup-host] i world] (send-off (agent i) e))) or (doseq [e [retire-host slowdown-host infect-hosts naturalrecovery- host pair-host breakup-host] i world] (send-off (agent nil) (fn [_] (e i)))))) There doesn't seem to be any concurrency happening, and the whole thing just slows down to not doing much at all. Anyone knows what I am doing wrong?. Considering that I wrestled with this before in previous posts in this group, I offer my apologies for not getting the correct way of mixing agents and refs into my thick skull. (Luckily I have grasped agents-only models, so there is hope :), but as I need refs in this model, I'm again banging my head against the wall). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
