[akka-user] Multi-agent Systems That Learn

2015-05-10 Thread Joseph Mansigian
I have a free open source prototype of a multi-agent system that learns and forms plans by conversing with members of a community of Akka actors. - each of which models the behavior of a different technology. Currently coded in one language - Java. Scala would be coded also if interest shown.

There seems to be no way to express this (simple) shape using a `FlexiRoute`. A naive version: class SplitShape[A](init: FanOutShape.Init[A] = FanOutShape.Name[A]("Split")) extends FanOutShape[A](init) { val whenTrue = newOutlet[A]("whenTrue") val whenFalse = newOutlet[A]("whenFal

@Olger Thanks for the detailed explanation of your approach. As Richard mentioned, it looks indeed like using persistent actor as durable queue. Is there any concrete effort started already in the direction of supporting this in Akka? Or at least there's some example implementations on this idea

Hello, I have read all of the documentation. I am missing a simple overview that contains the different types of elements. As far as I can tell there are two things: Graph and Stage. A graph has a `shape` which describes it's input's and it's outputs. There are a few specialized shapes which a

Thanks. So I guess you're basically using a persistent actor as a durable queue, in place of something like a Kafka topic, and a single message on the queue can include ids of multiple aggregates. On Sat, May 9, 2015 at 10:51 AM, Olger Warnier wrote: > Hi Richard, > > I use the akka cluster shar

Hi All, I have a graph consisting of 2 parts: The first part is a flow that connects to an irc network, it looks something like this: Source[IrcMessage, Unit] The second part is a flow that is materialized once per client connection (websockets: Flow[Message, Message, Any]). The goal is to h
