Hello!

I was thinking about rewritting this project to ES6. Since a lot of part can be rewritten and some test could be added :D

Hey, I'm trying to run the graph.js example. The documentation only says I have to run node --harmony graph but it throw errors after installing the npm dependecies. ¿Could you please explain me if I'm doing something wrong or what dependencies versions do I have to have to run this example correctly?

Thanks in advance.

Hi, your library looks great. Can you please tell us what PDDL specification you support (1.2, 2.1, 3.1 ...?).

Thank you!

If you try to install and run strips today you'll also get the latest version of pegjs; they've chenged the name of the function "peg.buildParser" to "peg.generate", so you'll have to change it manually in strips.js:32 for the whole thing to work without errors.

It would be great for beginners like me to have some instructions on how to run the system.

I'm really interested in AI and am on lecture 5 of this series http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-034-artificial-intelligence-fall-2010/lecture-videos/

I'm thinking it'd be fun to try a stock market AI using node.js. Can you guys give me some high level concepts that the program would probably use to accomplish the goal of predicting stocks performance?

I was thinking you could do market size based on google searches and then look at where the search trend is expected to head...

Also, there's something called "sentiment analysis."

Could you guys give me some guidance and direction here? I feel like a breadth first search, going in every direction.

Hello,

I'm trying to study PDDL and planning technologies. I was trying to use your example "magicworld" and I could not write in domain a new definition for "move". My idea for "move" is a new precondition using "OR" operator for border, like:

to change
:precondition (and (at ?p ?l1) (border ?l1 ?l2) (not (guarded ?l2)))
for
:precondition (and (at ?p ?l1) (or (border ?l1 ?l2) (border ?l2 ?l1)) (not (guarded ?l2)))

However, I did not find anything about "OR" operator in PDDL yet. Then, I thought in DeMorgan's Law, and I tried:
:precondition (and (at ?p ?l1) (not (and (not (border ?l1 ?l2) ) (not (border ?l2 ?l1) ))) (not (guarded ?l2)))

But, I obtained stranges results:

- Solution found in 1 steps!
1. move npc town castle

The expected result was:

- Solution found in 2 steps!
1. move npc town field
2. move npc field castle

I fork your project and I put my change in a directory "mymagicworld"

Forgive me the inconvenience and thanks for any help!

Does strip support quantifiers?

I am getting the following error

• node: 12.14.1
• strips: 0.0.10
• pegjs: 0.10.0

I would be happy to provide the files as well if needed.

This is fascinating! Could you please elaborate the anomaly solution more? I don't understand:

What the x represents
What makes an anomaly

Thank you!

• In the branch mutex, implement the algorithm GraphPlan to solve a planning graph by correcting and completing the method named solve() and associated methods for marking mutexes.
• The implementation should reside in graphplan.js
