Hi, how is the state of work on this issue? I'm starting to implement it, how 
can I send you my code when i finish it?

Thanks

Hi,

Currently no one is working on this. I'll be happy to accept your contribution 
into the code base once you've completed it (be sure to indicate your 
authorship in the javadoc at the head of the files you contribute). You can 
email it to me at ctjoreilly@gmail.com. FYI It'll likely be towards the end of 
March before I can integrate it properly and create a release containing your 
contribution (I'm currently swamped with work/classes).

Thanks

Ciaran

I faced some problems with this implementations, in particular with the 
knowledge base. For example, some temporal sentences needed by the algorithm 
are too long to be processed by "askWithDpll" function (it goes out of memory 
in CNF conversion). So tests is are impossible to be done, at least with my 
notebook.
The only tested parts are "plan-route" and "plan-shot" functions.

Is there a solution? If you are interested on this work anyway, i can email it 
to you.

Federico

Hi,

No problems, feel free to send me your code and I'll have a look over it. It'll 
be a couple of weeks before I can look at in detail. Off the top of my head I 
think 2 things may need to be done:

1. The CNF implementation of propositional formulas likely needs to be 
revisited (I've been meaning to do this for a while).

2. To handle temporal sentences it may be necessary to use a specialized 
inference algorithm, though for simple examples we should be ok.

Thanks

Ciaran

Related comment as regards code:

Hi, 
this is the code we wrote to implement the hybrid wumpus agent pseudo-code. We 
waited because we tried to fix CNF conversion but we don't have positive 
results yet.  So KB inference isn't tested because of CNF conversion goes out 
of memory everytime, anyway components about A* search (panRoute and planShot) 
seem to work well. 
We hope our little work can help this project.

Federico Baron, Alessandro Daniele
