Assignment 1 - Autonomous Software Agents

The project consists in building a PDDL/MA-PDDL national vaccine distribution domain and problem, according to the guidelines specified into the ASA-assignment-1.pdf file.
First assignment for the Autonomous Software Agents course @ UNITN.

⚙️ Tools

• MetricFF, local planner on the provided Virtual Machine for the single agent version
• Maplan, local planner on the provided Virtual Machine for the multi-agent version

  Maplan doesn't support plenty of libraries useful to solve the problem (such as :conditional-effects or :fluents)

• PDDL Editor, online planner (works only with very small problems due to a server-side resource contrainsts)

🔧 How to use

• Clone the repository https://github.com/sebastianochiari/ASA-assignment-1
• If you are using the online planner, load the vaccine-domain.pddl file and the vaccine-problem-*.pddl (choose the full problem description or a small version) and click solve
• If you are using the local planner, execute the following command (all the files must be placed in the same folder of MetricFF)

  ./ff -o vaccin-domain.pddl -f vaccine-problem-*.pddl -s 0

📜 Report

The report asa-assignment1-report.pdf includes all the details about project specifications, domain and problem implementation and design choices, problems and error analysis.

📝 Small problem

A test environment with a small problem to be solved.

1 central point, 3 regions, 7 provinces, 15 health districts, 2 airports, 1 plane, 3 trucks, 3 drones and a total of 15 vaccine boxes to be distributed

This problem has been solved by using Metric FF over the provided virtual machine, with 14GB of dedicated RAM, in about 2 hours.

📝 Full problem

The full problem, satisfying all the contrainsts given with the assignment guidelines.

1 central point, 15 regions, 113 provinces, 412 health districts, 21 airports, 10 planes, 22 trucks, 78 drones, 412 vaccine boxes

The full problem is generated via generator.py, a Python script, and some additional .txt containing all the necessary information to build the complete problem: all the files can be found in the src/utils/ folder.

📝 Multi agent

Two possible implementation for the MA-PDDL can be found in the src/multi-agent/ folder:

• the working folder contains the biggest version of the implementation that the planner is able to solve.
• the attempt folder contains the full theoretical MA-PDDL version (not working because of maplan limitations)
