Tutorial of two parts
![Page 4: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/4.jpg)
The Good News You only have to write
ONE thesis Except you French and
Germans who have to do a habilitation
At the end, you can add “Dr” to your name Good for upgrades on
planes
![Page 5: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/5.jpg)
2nd half of the tutorial
![Page 6: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/6.jpg)
The Bad News Writing a thesis is
hard, painful work You’ve already done
the fun part (the research)
It’s unlike any other document Thesis writing is not
a marketable skill
![Page 7: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/7.jpg)
The Bad News Some people never
manage to write one 99% perspiration 1% inspiration?
If you’re lucky, your thesis will be read by: Your supervisor Your committee
![Page 8: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/8.jpg)
Why write a thesis? It’s the union card
for academia You all have to suffer
like we did!
In the procces, you will learn How to research How to write
![Page 9: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/9.jpg)
Why write a thesis? It’s the union card
for academia You all have to suffer
like we did!
In the procces, you will learn How to write
Shorter conference & journal papers will be easy!

Why write a thesis? You get to add “Dr”
to your name Great aunts, etc. are
most impressed
It will introduce you/your research to a wider audience Thesis committee …

Why write a thesis? It will make you
famous Unlikely Look at the statistics
It will radically change science Unlikely Look at the statistics

Why write a thesis? It will advance our
knowledge Just a little Main benefit is in
teaching you to research
It will be read by others Your thesis committee If unlucky, it will suffer the
same fate as my thesis!

Ok, when do I start? So I’m motivated When do I actually
start writing my thesis? 6 months before the
end of my grant?
![Page 14: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/14.jpg)
Ok, when do I start? So I’m motivated When do I actually
start writing? 6 months before the
end of my grant? No, the day you start
your PhD Write it all down!

What a thesis isn’t? What I did in the lab
over the last 3 years I first read the
background material I then implemented an
algorithm I ran some experiments …
A thesis is a logical reconstruction Not a historical narrative
![Page 17: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/17.jpg)
What a thesis isn’t? A brain dump of
everything you’ve done You get to leave out the
dead-ends But you have to fill in any
obvious gaps!
A thesis is a logical reconstruction With a single coherent
message
![Page 18: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/18.jpg)
What a thesis isn’t? Available to buy
Even if www.thesis-master.com offer you one at $15/page
I wish I got those rates!

What is a thesis? Demonstration of an
understanding of the state of the art Critical appreciation
of existing work A novel contribution
Evaluated systematically

So, how do I start? Write a thesis message
1 sentence 1 paragraph 1 page
Everything you write should be directed at this Thesis (noun).
1. A proposition maintained by argument
2. A dissertation advancing original research
![Page 24: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/24.jpg)
Thesis message You’re tackling an
important research problem E.g. symmetry in CP
You’ve made an original contribution to its resolution E.g. efficient and effective
global constraints for breaking symmetry
![Page 25: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/25.jpg)
Zeynep’s thesis message
To deal with a common type of symmetry in CP, we propose some ordering constraints and develop novel algorithms for efficiently and effectively propagating them.
Row and column symmetry is a common type of symmetry in CP. Existing methods have difficulty dealing with the exponential number of symmetries in a problem with row and column symmetry. We therefore propose some ordering constraints which can effectively break such symmetries. To use these constraints in practice, we have developed some efficient linear time propagators. We demonstrate their effectiveness on a wide range of problems.

Make a timetable Targets to meet Light at the end of the
tunnel
Prepare your committee
![Page 33: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/33.jpg)
Timetable How long will it take? Depends on many
factors How much you’ve written
as papers …
Heavy-tailed distribution Min = 2 months (v. rare) Max = infinity Mean = infinity Median = 6-9 months
How long is a piece of string?
![Page 34: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/34.jpg)
Timetable “Your thesis is your
baby” P. Prosser Give it 9 months
Write it up Fill in gaps, expts …
“You have to know when to let it go” Put a fence around
what you’ve done
![Page 35: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/35.jpg)
Thesis committee Who should be on your
committee? Ideally you and your
supervisor will come to a mutual decision
Important, well-known researchers People notice if your
committee was “tough” You’ll get good feedback They may employ you They may recommend you
to others
![Page 36: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/36.jpg)
Thesis committee Why decide your
committee before you start writing? You can target your
thesis at them They’re busy people
Even busy people have open dates in their diaries a year ahead
They’ll still manage to schedule other events on the day of your viva
![Page 37: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/37.jpg)
What next? So, I’ve got a good
thesis message And a table of
contents, timetable and committee
What do I do next?
![Page 38: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/38.jpg)
What next? So, I’ve got a good
thesis message And a table of
contents, timetable and committee
What do I do next? Work to your
timetable!
![Page 39: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/39.jpg)
Writing each chapter Don’t start with the
Introduction or Conclusion
Start where you feel happiest Typically a middle chapter Write outwards Finally Conclusions and
end with the Introduction Write everything with
your thesis message in mind
![Page 40: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/40.jpg)
Writing each chapter Get feedback before
you write too much One person to read each
chapter as it is written Another person to read
thesis in order Lay some good
groundwork LaTeX macros Bib file Indexing …
![Page 41: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/41.jpg)
Writing each chapter You’ll discover holes in
your research Theorems you haven’t
proved Experiments you didn’t
run Different problems or
parameters
Mix writing with more research
![Page 42: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/42.jpg)
Rule of Three Within each chapter, repeat
yourself 3 times Intro. We will show .. Body. Show them .. Concl. We have shown ..
Within thesis, repeat your contributions 3 times Intro chapter Main chapters Conclusion chapter
But don’t bore reader E.g. in introduction be brief, in
conclusions be broader
![Page 43: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/43.jpg)
Common mistakes Informal text
Examiners will jump on imprecision
Opinions“.. The main problem in CP
is modelling ..” A thesis is an argument!
“.. A major bottleneck preventing the uptake of CP is modelling [Freuder, AAAI-98]

Common mistakes Complex sentences
full of long words A thesis should be a
simple, convincing argument!
Entertainment or humour Joke footnote
![Page 45: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/45.jpg)
Common problems It’s never possible to
cover all issues So you will never
finish?
![Page 46: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/46.jpg)
Common problems It’s never possible to
cover all issues So you will never
finish? It’s sometimes
enough to identify the issues
Examiners greatly appreciate you identifying limitations
![Page 47: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/47.jpg)
Common problems It’s never possible to
cover all issues So you will never
finish? It’s sometimes
enough to identify the issues
Examiners greatly appreciate finding a few mistakes
![Page 48: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/48.jpg)
Common problems Much of your thesis is
joint work Identify some work that is
yours alone Include a statement at the
start of your contributions:
“Results from this thesis appear in the following publications. Whilst much of this thesis is joint work with my supervisor, I made significant contributions to Chapters 3-6. In particular, … . “
![Page 49: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/49.jpg)
Common problems Ideas become
obvious to you You stop writing to a
sufficient level of detail
Especially hurts the opening chapters as they are often written last
![Page 50: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/50.jpg)
Common problems Writing too much
There are rules about maximum length
But rarely rules about the minimum
Nash’s PhD thesis 27 pages long Won him a Nobel prize
Je n'ai fait celle-ci plus longue que parce que je n'ai pas eu le loisir de la faire plus courte. Blaise Pascal, 1657
![Page 51: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/51.jpg)
Common problems At some point, your
brain will surely become toast Take a break Eat properly,
exercise, sleep …
Toasted brain is only temporary Just look at me?
![Page 52: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/52.jpg)
What to expect from your advisor?
Your not in this on your own
Your supervisor is on your side Your success is their
success
![Page 53: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/53.jpg)
What to expect from your advisor?
Intellectual support Quality assurance What standard a thesis
should reach Indication of when to stop
Emotional support Encouragement Constructive atmosphere
![Page 54: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/54.jpg)
What not to expect from your advisor?
Smiles If draft chapters contain
simple spelling mistakes and typos
Mind-reading skills Motivation dipping Absence = illness
![Page 55: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/55.jpg)
Defending your thesis Specific to the
country Private or Public? 2 to 9 jury members? Talk or Questions? Corrections allowed
or expected?
![Page 56: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/56.jpg)
Defending your thesis Don’t panic
You’re probably the world’s expert on this topic by now!
Your examiners are human They’ve sat in your seat They will help you find
what changes (if any) are needed to make this the required quality
![Page 57: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/57.jpg)
Defending your thesis Enjoy it
You’ve the world’s experts in the room
They want to talk about your work
How often will that happen in the future?
If you want, have a practice Get your supervisor to set
up a “dummy” jury Prepare your opening
statement
![Page 58: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/58.jpg)
What are examiners looking for?
Review of literature Is the literature
relevant? Is the review critical
or just descriptive? Is it comprehensive? Does it link to the
methodology in the thesis?
Does it summarize the essential aspects?
Methodology Is there a clear
hypothesis? Are precautions
taken against bias? Are the limitations
identified? Is the data collected
appropriately? Is the methodology
justified?
![Page 59: How to Write a Thesis](https://reader034.vdocuments.net/reader034/viewer/2022042703/56812aaa550346895d8e6f6b/html5/thumbnails/59.jpg)
What are examiners looking for?
Presentation of results Have the hypotheses
in fact been tested? Are the results shown
to support the hypothesis?
Is the data properly analysed?
Are the results presented clearly?
Are patterns identified and summarized?
Discussion and Conclusions Are the limits of the
research identified? Are the main points
to emerge identified? Are links made to the
literature? Is there theoretical
development? Are the speculations
well grounded?
