About This Course

Planning Algorithms are used in robotics, control theory, artificial intelligence, puzzles, games, algorithms, computer graphics, and even molecular motions. There have been many exciting developments in the planning field in the last few years, with current research focusing on the development of novel, efficient, and general algorithms for planning in these domains.

Each domain has different planning goals to achieve. In robotics, planning problems addresses problems such as uncertainty, coordinating multiple robots, and the integration with complex controls. In AI, planning helped find a way from a start state to a goal state. However, recent research has extended planning for puzzles and games through the use of information theory including Markov Decision Processes, imperfect state information, and game-theory. In biomolecules, planning is used to identify ways that molecules move in order to better understand diseases such as Mad Cow disease.

Even though these domains, games, robotics, and biomolecules, sound distinct, they share common ground in planning. In this course, we will discuss the current research in planning. In the process, each student will develop a project in planning that is suited to their domain interests.

Policies

Description:

Analysis, implementation, and comparison of planning algorithms, including complete, heuristic-based, and intelligent algorithms; examination of methods applied to multiple domains including robotics, gaming, and molecular motions. Graphical interface to visualize motions will also be explored.

Prerequisites:

Students need to be proficient at object oriented programming in either Java or C++. Students should have taken some higher level computer science courses. Possible courses include artificial intelligence or software engineering. Undergraduates interested in taking this course should speak with the instructor.

Topics:

Each topic will take 1-2 weeks. Each topic will include reading of related papers; students will write a summary and discussion of each paper. Each student will prepare and deliver a presentation based on a current or historic research paper. For some topics, programmatic assignments will be assigned. Students will develop a final project as part of the course. Students will have to write up results in journal formal and present their results.

Grading:

  • Homework: 50%
  • Topic Presentation: 10%
  • Project: 30%
  • Class Participation: 10%

All assignments will be announced in class and posted on the course web page. If you miss class for any reason, it is your responsibility to find out what assignments you missed.

No late homework assignments will be accepted. Please discuss unusual circumstances in advance with the instructor.

Submit your reports either in electronic format over email or printed directly to the instructor.

Note, that once the presentations for the project have been scheduled, they cannot be moved easily. Failure to present on time, will result in a lower final grade.

Project:

Students will be expected to do a term project. The possible topics vary widely. Possible topics include:

  1. Planning smooth camera motions in virtual environments
  2. Planning for a racing game
  3. Anytime planning, especially for systems with dynamics, such as cars, helicopters, airplanes, spaceships, etc.
  4. Replanning, especially for systems with dynamics
  5. Computing good quality paths for high-dimensional systems
  6. Sensor-based planning
  7. Planning under uncertainty
  8. Formation control
  9. Planning for mobile sensor networks or network-guided motion planning
  10. Planning with minimalistic information and representations
  11. Planning involved in protein folding

Students will write a description of their project expressing why the techniques used were appropriate and why. Students should also thoroughly evaluate their algorithm.

Academic Integrity: For everyone's benefit, students should uphold the guidelines in the University of New Mexico Student Code of Conduct.

For the assignments in this class, discussion of concepts with others is encouraged, but all assignments must be done on your own, unless otherwise instructed. If you use any source other than the text, reference it/him/her, whether it be a person, a book, a solution set, a web page or whatever. You MUST write up the solutions in your own words. Copying is strictly forbidden.

Americans with Disabilities Act (ADA) Policy Statement: The Americans with Disabilities Act (ADA) is a federal antidiscrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities.

Mac
Tex on Max OS X
MacTex

The first link describes many alternatives that are available for installing Tex on a Mac. The second link forwards to the MacTex package, one of the alternatives mentioned in the first website. MaxTex provides everything that you need to use Latex on Mac except from a text editor. It is, however, compatible with a wide variety of popular editors (e.g., Alpha, BBEdit, Emacs, VIM, iTeXMac, TeXShop). Note that MaxTex is a large package.

Carbon Emacs has been successfully tested with MacTex. After installing MacTex, it is possible to directly compile and view *.tex files from Carbon Emacs's UI.

Note for Mac users: You will probably have problems previewing your PDF output when using the postscript images provided by the instructor for developing the notes. Nevertheless, the PDF file can be printed properly. Prepare your document without the images and then add them. You will probably still be able to preview the intermediate .dvi output file with the "xdvi" program.

Linux (Ubuntu)
Latex on Ubuntu
Tex Live

You just have to download and install the proper packages described above (e.g., through apt-get), use your favorite editor (e.g., emacs) to prepare a *.tex file and then you compile (run at least two times: "latex filename.tex") to get the *.dvi output. You can go from dvi to postscript with the command "dvips" and you can convert postscript to pdf with the command "ps2pdf".

Windows
Latex for Windows help
MikTex (Latex for Windows)

If you follow the instructions on the first link you should be able to get it working on a Windows system.
