Human-like Artificial Agents (Summer 2020/21)

In this course, we will study human-like artificial agents, that is autonomous intelligent agents situated in a virtual environment similar to real world that act like humans. The course gives an overview of types of such agents and their architectures with the emphasis on the problem of action selection. The course also focuses on solving practical issues related to real-time and partially observable environments. The course is taught at MFF UK as NAIL068.

Terms

Terms differ according to the field you’re coming from. MFF UK students has different terms from FF UK students and vice versa. While there is also some common part for all.

Common Terms

Both MFF and FF UK students will be required to attend to a play testing targeting “fun aspect” of a game. Details to be filled in later and announced. Then both type of students will have an exam, but that exam will be different for MFF and FF UK students.

Exam for MFF UK Students

Exam for MFF UK students is highly practical. There will be no oral examination (unless you want it as ‘extra’) but you will have to create either a team-oriented behavior either for Pogamut 3 bots or a behavior for a NOTA robot squad. Details are available at Labs webpage (see above).

Exam for non-MFF UK Students

Be able to talk about general ideas behind: finite state machines, if-then rules; path-finding, steering, terrain representation

Labs for non-MFF UK Students

Either a machinima in Storyfactory [storyfactory.cz] or a watering garden task in Scratch [https://scratch.mit.edu/] (see below)

If you opt for Scratch, you should follow Scratch self-studying and
complete the final task as follows:

  1. Go through the basic tutorials [https://scratch.mit.edu/help/videos/#] — deadline 31 March
  2. Make a game as described in the tutorial “Make a simple game” — deadline 31 March
  3. Contact Cyril Brom; online consultations between 1 April — 14 April, you will show your programs (you can contact Cyril sooner, if needed)
  4. Make the Pong game [https://scratch.mit.edu/projects/editor/?tutorial=getStarted] — Click on Tutorials and Pong game — deadline 14 May
  5. Make the Clicker game [https://scratch.mit.edu/projects/editor/?tutorial=getStarted] — Click on Tutorials and Make a clicker game — deadline 14 May
  6. THE FINAL TASK for the final evaluation: Make your own virtual garden with
    • a virtual gardener having a simple reactive plan, a few rules
    • a virtual garden that can be dry or wet or something in between
    • a watering can — a barrel with water that can fill in the can when the gardener comes to its proximity
    • a magical button that empties the can instantly and fills the can with water instantly
    • a magical button that makes the garden dry / wet instantly
    • the gardener’s task is to take the watering can, fill it with water and water the garden; but (!), the user can play with magical buttons anytime and the gardener has to react appropriately — deadline 14 May
  7. Contact Cyril Brom; online consultations between 15 May — 31 May

You can contact Cyril sooner, if needed, you will show your programs (at least the watering task)

If you opt for Storyfactory, drop Cyril an email till 30 March.
