Re: [Repast-interest] network generation: could not find matching constructor

[Zhanna * <zha...@go...>]

Hi Jonathan,

I tried this piece of code in ModelInitializer (after I added all the agents
to the context "zhanna"):

// This is a task.
        NetworkGenerator gen=new WattsBetaSmallWorldGenerator(0.5,4,false)
        Context context = FindContext("zhanna")
        NetworkBuilder builder= new
NetworkBuilder("SmallNetwork",context,false)
        builder.setGenerator(gen)
        Network net=builder.buildNetwork
        // End the method.

And I get only nodes on the display without edges and the errror log says:
