Designing Intelligent Agents
Coursework
Colin Johnson
Overview
The coursework for this module is based around you designing intelligent autonomous
agents and an environment with which they interact, setting those agents a task, asking one
or more questions about that task, and evaluating it using experimental methods. You will
then present the results from this in a report, which will also explain the context for the work. Details
An autonomous intelligent agent is a program that operates in a particular environment, perceives aspects of that environment, and then carries out actions that change that
environment to carry out some task. Typically, these actions are a mixture of responses to its
perception and proactive actions such as exploration. Your task for this coursework is to design an agent-based system containing the following
four aspects:
An Environment. This is the (virtual) place where the agents will operate. It could be one of: ? A simulation of a physical environment in which mobile robotic agents move. This
could be the simulation used in the classes earlier in the semester (perhaps
extended), a robot environment such as The Player Project
(http://playerstage.sourceforg...), or a project in Unity or a similar game
environment if you are familiar with one from elsewhere. ? A chatbot environment such as the ones used in the classes. ? The blackboard system used in the class where we discussed language agents
writing poetry
? The Bristol Stock Exchange system introduced in the classes later in the semester
(https://github.com/davecliff/...) or a similar simulation of some
aspect of the economy or society
? A game environment such as Ms. PacMan (https://gym.openai.com/envs/M... v0/), the Open Racing Car Simulator (http://torcs.sourceforge.net), RoboCup
(https://www.robocup.org/leagu...) or similar (see e.g. http://www.gvgai.net) ? One of the more complex task environments from the OpenAI Gym
(https://gym.openai.com)
There is no need to develop the environment yourself—the focus of the project will be on the
agents in the environment (chatbots, robots, trading agents, game-playing agents, autonomous drivers, etc.) – but it is likely that you will set up the details of the environment
to address your specific question. You are allowed to use the code from the classes, but
please try to make it clear broadly which parts of the code are taken from the class examples, and which is your own work (we appreciate that this is sometimes complicated to do at a
line-by-line level, but you should indicate this in broad terms). Autonomous Agents. You should introduce one or more autonomous agents into the
environment, which use some kind of AI to solve a task.
? Examples of AI could be an AI planning system such as Goal Oriented Action
Planning (http://alumni.media.mit.edu/~...), a search algorithm such as
A* search, a genetic or swarm search, a reinforcement learning algorithm, fuzzy logic, or a hard-coded reactive or state-machine AI. ? The task will be one relevant to the environment: e.g. a robot vacuum cleaner
clearing up dirt, a chatbot taking an order from a customer, a trader trying to optimise
its returns, a game player trying to get a high score in a game, etc. Within reason, you can use any language to do this. If you are planning to use anything
other than Python, Java, Matlab/Octave, JavaScript, and standard web technologies such as
HTML/CSS, then please mention this in your topic approval. A Question. You should be asking a specific question (or a set of related questions) about
your system. For example: ? How do different approaches (a genetic algorithm, an A* search algorithm, a hard- coded heuristic) compare in terms of task performance?
? How does the performance of the system change as we vary the number of agents in
it?
? If the system is trained on one version of the environment, does that learning transfer
over to a new version of the environment ? How do different kinds of communication/coordination between agents effect the
efficiency of those agents on the task
? How much improvement does storing some information (e.g. a map of the
environment) make compared to carrying out the task in a purely reactive way?
? How do different kinds of sensing/perception systems affect the capacity of the agent
to carry out its task?
? How sensitive is the agent to error/noise?
A Set of Experiments. You should answer your question by carrying out a set of experiments. Remember the structure that we talked about in one of the lectures: ? implement code that carries out a run of the agent’s behaviour and measures
performance
? then, run that code multiple times to get a measure of average performance
? then, repeat that process for the different conditions in your question, and use
descriptive statistics, charts/visualisation, and/or inferential statistics (e.g. significance tests) to test your question
Then, you are in a position to discuss the question using these experimental results as your
evidence. Examples
Here are a few examples of things that you could do. You don’t have to do one of these—
indeed, we would prefer you to come up with your own idea—but, these would all be
acceptable project ideas if you want to do them: ? To take the “robot vacuum cleaner” from the early classes, and experiment with
different numbers of robots, and different coordination strategies (e.g. robots try to
stay a fixed distance from each other, compared to sharing a map that they build up) ? Contrast random, fixed and planned orders of asking questions in a chatbot, and see
(perhaps by doing a brief user test) which one is better. ? Take a number of different trading strategies and run them in the Bristol Stock
Exchange system with varying amounts of noise/uncertainty, to see how robust each
strategy is.
? Take the “avoid the cats” problem from the class, and compare a number of
strategies for the problem: warning the cats vs. moving out of the way, and learning
when to act based on a simple statistical approach vs. a decision-tree approach. ? Consider the problem of planning a robot’s movement around a mapped environment
(e.g. the map generated from WiFi triangulation introduced in one of the classes). Contrast A* search and genetic algorithms on this problem, and compare them both
against random wandering. Topic Approval
You should submit a short description of your project idea (around a paragraph, 100 word)
on the Moodle page by 15:00 on the 7
th May 2021. We will then give you feedback on
whether the project is an acceptable one, and how it might be modified or improved. You do
not have to wait until then before submitting your idea;
we will start looking at them from mid- April onwards. Submission
By 3pm on 18
th June 2021 should submit the following. This may be extended if you have a
support plan or extenuating circumstances. Late submissions will incur a penalty of 5% per
working day, up to 25
th June 2021, after which you will receive a mark of zero. COMP3004

clearly state the question that you are trying to answer ? A review of relevant ideas, technologies and research papers
? How you designed the environment and agents in order to address that question
? Technologies used, and challenges that you met in doing the implementation
? How you set up and ran your experiments
? The results from your experiments
? A discussion of the question in light of the experimental results
? A conclusion, where you summarise the work, reflect on its successes and limitations, and briefly mention some ideas for how you would take the work forward if you had
more time

Anything else that you think would be helpful for the markers, e.g. sample outputs from your
system, a link to a brief video demonstrating it working, etc. COMP4105

Anything else that you think would be helpful for the markers, e.g. sample outputs from your
system, a link to a brief video demonstrating it working, etc. Academic Integrity
This is an individual assessment that should consist of your own unaided work. You should
make any direct quotations clear both by using quotation marks and by providing a clear
reference to the paper immediately after the quotation. If you are building on someone else’s
code (e.g. our code from the classes, open-source projects, etc.), please make it clear which
aspects of the code are your work through the use of comments. The University has detailed
advice about academic integrity, and submissions that demonstrate a lack of that integrity
will be treated under appropriate disciplinary procedures. How the Work will be Marked
Marking will take into account: ? background research and how you have used it to contextualise your work
? the choice of task environment and how you have used it/adapted it for your specific
project ? the effective use of artificial intelligence and agent-based systems ideas from the
course and your wider studies in designing your autonomous agents
? how clear your question(s) are, how well the experiments have been designed to
answer them, and your level of rigour in planning and analysing the experiments
? how well the report answers the question by using the evidence from the experiments
? the overall clarity and structure of the report, appropriate use of scientific and
technical English, and the quality of charts, diagrams, pseudocode where relevant ? the quality of reflection on the successes and limitations of the work
? (for students doing a presentation) the structure of the presentation, the clarity of
explanations, and good use of slides or other visual aids
COMP3004 Marking Scheme
Each of the following descriptors gives a broad idea of the achievement expected for a mark
in that range. Clearly, individual projects may fall short in some areas and show excellence
in others. The marking should also be adjusted to reflect the intrinsic difficultly of the project. Band Guidelines
90-100 Marks in this range are reserved for a superb all-round performance. Work done in
all aspects of the project go beyond even high expectations. The student has
shown a thorough understanding of the problem. All expected tasks have been
successfully completed, the project shows depth and engagement with research
ideas, and everything has been completed to a high standard. The report could
form the basis of a publishable conference/workshop paper. 80-89 Excellent contributions to all areas of the project. Exceeded expectations in some
areas. Demonstrates knowledge and understanding of the project that is beyond
standard resources covered in the module. Clear appreciation of the project as a
whole, its adequacies, limitations and possibilities for future development. The
project demonstrates insight and depth beyond that usually expected in
undergraduate work. 70-79 Very good contributions to all areas of the project. Successful completion of the
project tasks. Demonstrated initiative and creative problem-solving ability. Able to
undertake the work in a competent and independent manner. Able to reflect
accurately on adequacy and limitations of the project’s achievements. 60-69 Good appreciation of background. A good attempt at applying this to the task, with
demonstrated ability to cope with difficulties. Good technical skills in several areas. Whilst most of the core aims of the project have been achieved, it might come a
little short in some areas. Good reflective understanding of the project. 50-59 Satisfactory background reading and a competent attempt at their tasks. Reasonable technical competence demonstrated. The core task completed
satisfactorily, but little achieved beyond that. Able to reflect satisfactorily on the
project. 40-49 Pass level. Competent background reading and appreciation of the project area. Basic technological competence. Some areas of the core tasks may be
incomplete, but a decent attempt has been made at them. Able to reflect in a
limited way on the project. 30-39 Unsatisfactory. Some attempt has been made at the background reading but
clearly only partial understanding of project topic. Incomplete attempt at the core
tasks. Weak technical competence. Little ability to reflect adequately on the
project. 20-29 Inadequate background reading, but shows some limited understanding of how
ideas can be linked to the task. Minimal attempt at the core tasks, showing poor
understanding. A substantial amount of work is still needed to achieve the core
tasks. Minimal reflection on the project. 10-19 Minimal attempt at background reading, inappropriate use of material, almost no
attempt at core tasks. Very poor understanding of the problem. Minimal or no
reflection on the project. 0-9 No or almost no significant attempt.
