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

Hi Zhanna,
The last line needs to be:
Network net=builder.buildNetwork()
Otherwise, you're trying to access the property buildNetwork in the
build object (which explains the error below). This way you're calling
the buildNetwork method.
Hope that helps,
Jonathan
