Defining a domain in PDDL and using IPP

Due: Oct. 4

In this week's assignment you will translate your truck domain to PDDL and use it with IPP, a descendant of GraphPlan. IPP is available from the CS 541 home page, under the link for planners. Included in the distribution is the PDDL manual.

1. Translate your UCPOP domain to PDDL.
2. Test your domain on the same problem that you used with UCPOP, moving a package from one location to another. Test both the version where a truck can move only one package and where a truck can move an unlimited number of packages.
3. Investigate how the domain scales, i.e. how much extra time is required when you add more packages, trucks, locations etc. You can use the time information printed out by IPP to compare running times.

   In particular, compare the following three problems when a truck can move only one package at a time: moving five packages with one truck, moving five packages with two trucks and moving five packages with five trucks. Give a brief explanation of the behaviour you see.

4. Turn in a print out of your domain, initial state, goal state, and trace of a successful run. Describe the scaling behavior you found.
