Dear IPC-5 competitor, The third test domain ("trucks") is now available on olimpia from /home/ipc5/domains/trucks. I attach a short description of the domain and its variants. This file will be available also from the competition website. A few IMPORTANT notes (please take the time to read them): 1. Only very few of you have run the tests on the problems that we have already released. Please start running your planners as soon as possible, at least for the "traditional" domain variants (Propositional and Metric- Time). If the tests are delayed too long, you won't have enough CPU time to complete all tests!! This applies especially to those who are planning to use lot of CPU time (the teams that compete with more than one planner, or that have planners attempting many categories). 2. For all tests you run, please use the SAME COMMAND LINE for your planner. When you will send us the executable, you will have to send this information. 3. Please remember to send us an abstract (1-3 pages AAAI style) about your planner(s) by March 10. This is for a booklet that ICAPS'06 will distribute to the conference participants. If you have problems about meeting this deadline, please let me know. Thanks. Regards, Alfonso
