Dear Jason users,

thanks to the contribution of Maicon Zateli, we have a new eclipse plugin for Jason! It is still in beta release, but we invite you to try it and give some feedback and suggestions (by email to Maicon Zateli <xsp...@gm...>).

Hi, there

I am just wandering how to implement CASO agent mentioned in your 
Projects of Jason 
website.(http://jason.sourceforge.net/Jason/Projects.html).
I am trying to do work improving it.

There are two steps mentioned in the part of that paper--Modifying Jason.
Is there any extra steps?
If there is a separtate file for beliefs(as following) in constraint 
solver ECLiPSe, how we write beliefs in .asl file of Jason? If there are 
parameters for each actions in a plan, do we need to change the other 
codes, which Jason did not deal with that?

By the way, is there any examples in Jason that refers to the applicable 
plans?
Thanks for your help.

Regards

Jane

Hi,

Just wondered if anyone had looked at redirecting Jason log output to something else? I'm thinking of something like chainsaw, so I can sort/timestamp etc all of the reports I'm seeing from agents, as well as additional things like message/perception counts over time. At the moment I'm writing to disk but I'be now got alot of various parts doing alot of disk I/o!

Thanks!
