MAPF @ SoCS | |
This is a message I got from Sven Konig. Thought worth re-publishing if anyone is interested. ++++++++++++++++++++++++++++++++++++++++ The International Symposium on Combinatorial Search (SoCS) will be held from 26th - 28th May, 2020. Each year SoCS offers a unique opportunity to hear about the newest advances in the field of Heuristic and Combinatorial Search and to engage with some of the brightest minds working in those areas. SoCS attendees include world-leading academics, outstanding early career researchers and the next generation of leading young scientists. In this its 13th year the Symposium will take place online and our entire technical program and proceedings are being made available to all, including a larger number of talks on multi-agent path finding. This year SoCS has aligned itself with the 17th International Conference on the Integration of Constraint Programming, Artificial Intelligence, and Operations Research (CPAIOR). To celebrate we have will have special activities which aim to bridge the gap between the area of Heuristic and Combinatorial Search and that of Discrete Optimisation. Among the many highlights at SoCS 2020: - 25 talks across five technical sessions (plus two award winners!) - Keynote talk from Rina Dechter (SoCS plenary) - Keynote talk Peter Stuckey (special activity, joint with CPAIOR) - Master Class sessions (special activity) where leading experts will disseminate recent developments on a variety of exciting search-based topics. Every talk will be streamed live on YouTube and will be subsequently made available for viewing on-demand. HOW TO PARTICIPATE: 1. Follow our technical program from the SoCS homepage: https://urldefense.com/v3/__https://helios.hud.ac.uk/scommv/socs2020/main.php page=program__;!!LIr3w8kk_Xxm!7NqjdfE-WP13KDc7vU8NsxC6z2mDhwG6uIfNAYPOj04JhEG2VtWGzxNunpzQjA$ 2.

Grades for CBS project published | |
Hello, Grades for the CBS projects are published. In addition, I published a solution under "חומר המקצוע" so you can see the "formal" solution. A few notes on the grading (given out of 30): - For submitting the intermediate submissions (task 0-1 and 2) you received 2 points for each task. So everyone got 4 points automatically. - For successfully answering 2.5 you got 6 points. If you answered all of the subsections correctly and not only one, you got an extra two points. - For the CBS part (task 3) you got 15 points if the results were correct and optimal. - For task 4 you got 5 points if the results were optimal. - Partial points were deduced when the results were not optimal If you want to discuss your grades and receive more-specific comments on your submission, feel free to contact me.

Feedback and presentations available | |
Hi, Student presentations are available under "course material". Here is some feedback so hopefully other can learn: Both presenters did a great job. Presentation were visually appealing and clean and they did a great job in responding to the student questions and managing time. In general, I prefer that the language would be in English. * Moving Agents in Formation in Congested Environments * My biggest comment (which is small) regards the notion optimality that caused all of us some confusion should have been clarified. On a minor technical note - in the explanation of focal search, it was described as an absolute value (8 in your example) but it is actually a relative ratio from the f-value at the head of the queue. No citation was given for focal search. Some monior comments: recognized -> represented / described 4 neighbor grid -> 4-neighbor grid why [] and not () Total Formation deviation -> Total formation deviation * Lifelong Multi-Agent Path Finding in Large-Scale Warehouses. * I especially enjoyed the description of the empirical results which tried to provide some design considerations (e.g., why PBS outperforms CBS). Since PBS was shown to outperform other methods, it seems surprising that token-passing was explained and not on PBS. The presentation containing very little technical information and the presenter relied on his oral presentation to fill in the details. I think this caused long and vague descriptions resulting in some confusion among the students. Some minor typos: token passing algorithm -> token-passing algorithm requests -> requirements |

Guidelines for final report | |
Recall that the final report's objective is to force you to understand a paper that you did not present. This will constitute as 20% of your final grade (after the new point distribution). The report should be between 1-2 pages and should include: (1) A summary of the paper in your own words (0.5-1 page). Try to answer the following question "what is the ONE key insight that enabled the work of the paper?" (2) Directions for future work? (0.5 page) What is missing, how could the work be extended? (3) [BONUS] Design in detail a project around the paper (1 page) What are the outcomes (implement the approach is not a good project)? What are the expected results? What tools are required to implement the project? Oren |

Talks at AAMAS 20 | |
Hi all, The International Conference on Autonomous Agents and Multi-Agent Systems will be held online (via recorder talks) this year free to all. The talks we heard yesterday will be presented there. The first one is already available at https://underline.io/lecture/375-moving-agents-in-formation-in-congested-environments If you are interested in the other one, it will appear in the upcoming days at https://underline.io/conferences/19 In addition, there is an interesting paper, Multi-Agent Path Finding in Configurable Environments by Matteo Bellusci, Politecnico di Milano The talk is available at https://underline.io/lecture/278-multi-agent-path-finding-in-configurable-environments I encourage you to check out the talks and any additional ones you find interesting.

Changing grade distribution | |
I understand that Task (4) in the CBS project was much more time consuming than expected. To accommodate for this, the final report will be smaller and will constitute only 20% of the grade. The CBS project will be 30% of the grade with the fourth task being only 5 out of the 30 points. This will allow students who did not complete Task (4) at all to still get a very high grade (95) and to reduce the workload at the end of the semester. Looking forward to hearing your talks, Oren |

Intermediate submissions | |
I opened a "HW" for the submission of task (0) and (1). For the intermediate submissions, please submit just the code. This is just a sanity check that all students are all on the same page. I will give 0 or 2 points for each intermediate submissions (on dates 29.3, 7.4 and 26.4) . The real grading (rest of the 14 points out of 20) will be given when the mini-project / HW is submitted. Here you will have to attach a small text describing your implementation, answering questions (e.g., 1.5 that we discussed yesterday) with some screenshots. |

Corona virus and seminar - update (2) | |
Following the fact that we are forced to meet virtually and not in person,I decided to slightly change the seminar's format. I will discuss this in detail on the Wednesday's zoom lecture but the high-level summary is that I don't think it will be effective to have students give a two hour-lecture. Instead, we will spend the first part of the course doing a mini project that will give us hands-on experience with MAPF algorithms. Student lectures are postponed to after Independence day and will span only one academic hour per students. I know these are difficult times and uncertainty is high. Feel free to contact me personally regarding any issue and I will try to respond as soon as possible. Oren |

Corona virus and seminar | |
As you know we are all uncertain regarding the next few weeks due to the outbreak of the Corona virus. Currently, the restrictions we have do not preclude us from having lectures with less than 100 students so we will meet as scheduled next Wednesday (13.8) at Taub 8. However, we are planning for the case where we will have to give the course virtually. If this will be the case, we will use Zoom to give the lectures, and discuss them. Please make sure that you have access to a computer with a good microphone and a webcam. I will keep you posted once things clear up. |
