Welcome to Pweak's planning refuelling-station on the Infobahn!

Refill both yourself and your best friends with planning diginformations:

• Retrieve the Pweak planning system,
• Jump to other planning rest stops,
• Retrieve planning fuel from specially chosen planning systems,
• Attend planning cybercourses,
• Get planning conferences diginformations,
• Sense digixotic planning diginformations,
• Learn about the version of Pweak© and Open-Prolog© on this site.

Refill both yourself and your best friends with the Pweak planning systems

Pweak's planning abilities are that of classical planning (positive atomic formulas, Strips action description, a plan is a partial order, plan modification planning is in the partial plan space).

Not only can you simulate the usual planning procedures of the literature (such as Tweak, SNLP, UA and those that Refine-Plan can simulate) but also you can degrade these procedures in selecting some parts of them, or else build new ones.

To simulate a planning procedure, (Macintosh) menus and dialog boxes are provided.

A Mathematica® package is provided to analyze the search space visited by the planning procedure which was simulated. With the functions of this package you can:

• visualize the search space together with some numerical computations (e.g. mean radius of gyration, the center of mass, etc),
• compute the probability of appearance of a partial plan in the partial plan space,
• visualize the node-step lengths of the search space,
• compute the probability of appearance of a node step length in the partial plan space.
• compute the box dimension of a search space (based on the visualization above).

If you do not have access to Mathematica®, you can nevertheless consult the files with MathReader, a freely available program that will allow you to read (and print) any Mathematica® notebook on most computer platforms (and, in particular, on the Mac!).

More than 90 planning problem examples (from the literature and others) are provided.

All the prolog and Mathematica® sources are provided.

Don't hesitate to report unexpected features (bugs, I mean). You can also refill your best asciinformation reader (you, of course) with:

• Pweak's manual document (don't hope too much!).
• Pweak's releases document.

Note these two documents come for free when retrieving the informadditive Pweak.

And when your postscript interpreter feels hungry, don't hesitate to feed her with some great postscrinformations of mine about planning abilities.

Make yourself comfortable in the planning field!
