1 ModPlan ModPlan – Moderne Handlungsplanung (Modern Action Planning) PD Dr. Stefan Edelkamp Shahid Jabbar (ich) Tilman Mehler

2 ModPlan Planning Task  Given: An initial state I. Set of actions that transform a state into another state. A goal state G.  Task: Find a sequence (possibly shortest) of actions that can transform the initial state to the goal state.

3 ModPlan A Typical Planner Domain DescriptionProblem Pre-processing Search Heuristics Plan Planner

4 ModPlan Types of Problems  Basic I am at home and I want to go for grocerry shopping using public transport.  Mertic I do not have much money but I need to buy the grocerry for the whole week.  Temporal Today is Saturday, shops are going to be closed at 18:00.  Non-deterministic (She loves me, she loves me not) What if my girl friend calls just before I have to leave for shopping.  Probabilistic Borussia Dortmund vs. Bayern München in Westfallen Stadium – might be some traffic jams.

5 ModPlan Typical Approaches  Local search  Constraint satisfaction  Linear programming  Satisfiability problem  Evolutionary algorithms  Scheduling problem

6 ModPlan International Planning Competition  The biggest event in the Planning community.  Planners are compared for their performance on test data sets.  Planner MIPS (Edelkamp) was awarded the ‘Distinguished Performance’ award in 2000 and 2002 competitions.

7 ModPlan PG Task  Implement the existing state-of-the-art planning algorithms and your own ideas.  Compare your results with the past results from the International Planning Competition.  Hopefully, participate in the next International Planning Competition.

8 ModPlan Extras  What if your state space does not fit into the main memory ? External memory searching algorithms  What if I want to see the searched plan in a more user-friendly way. Visualization of Plan. Existing Client-server architecture – VEGA (Visualization of Efficient Geometric Algorithms)

9 ModPlan Frequently Asked Question  Is the PG in English or Deutsch ? Sie ist auf Deutsch.
