- Written Exam, 2014-05-28
- Oral Exam, between 2014-06-02 and 2014-06-03
All assignments are done individually.
Assignments from Text Book
See schedule. Will be updated.
At the end of the course, each student will have an oral examination, where you
must bring solutions to
(i) all mandatory assignments, and
(ii) at least half of the other assignments.
Your solutions must be nicely printed (not handwritten, but it is ok to include handmade figures if they are nicely done)
The level of detail should be roughly as the explanations in the book.
Other Assignments
These assignments have to be handed in by the deadline in an open and widely adopted format (such as PDF).
Assignment 1
- 1a: Use Citeseer or Google Scholar and try to find the most cited paper presenting a solution to the Traveling Salesman Problem (TSP).
- 1b: Find, using Citeseer and/or any search engine, your own favorite paper on TSP and make a four-slide executive summary.
- You should deliver
- (i) Title, author, journal/conference etc of the most cited paper,
- (ii) the same for the paper presenting the best solution (in your opinion),
- (iii) plus a 4-slide executive summary of your favorite paper.
Email your solution to Karl, make sure to write "AdvAlg" in the header.
Make sure your own name is clearly written on the solution.
Deadline: See Schedule
Assignment 2
- 2a: Find your favorite paper on Tabu Search and write a 2 page executive summary.
- 2b: Do the same for your favorite paper on Simulated Annealing.
- 2c: Do the same for your favorite paper on Genetic Algorithms.
Deadline: See Schedule
Assignment 3
Find a good paper on algorithms and/or optimization, preferrably from a ACM or IEEE journal or conference. Write a 2-3 page executive summary, make a 5-slide presentation.
Hint: Use Uppsala University Library's List of Journals to get access to all major journal and conference homepages. Examples of good journals include, but are not limited to, SODA (Symposium on Discrete Algorithms) and FOCS (Foundations of Computer Science).

- The art gallery problem Given a polygon-shaped art gallery with n sides, what is the minimal number of guards that need to be placed in the gallery so that they see every corner of it? There are museums with 3n walls for which n guards are required. On the other hand, floor(n/3) guards are enough for any n walls museum, but an algorithmic problem could be to determine the positions of them. http://mathworld.wolfram.com/ArtGalleryTheorem.html

- Solving Rubik's Cube. Maybe too famous, there are solutions at, e.g., http://helmsoft.org/cube/rubikscube
- Given a finite set of building blocks consisting of several 1x1x1 cubes (or, in the 2d version, 1x1 squares) glued together at facets, put them together into a big cube (rectangle) of given dimensions. The Slothouber-Graatsma Puzzle http://mathworld.wolfram.com/Slothouber-GraatsmaPuzzle.html and Conway's Puzzle http://mathworld.wolfram.com/ConwayPuzzle.html are special cases.
- Magic squares: How to generate magic squares (nxn matrices with constant row, column, and big diagonal sums). The magic squares are obviously solutions to a linear equation system so they form a subspace of the space of all nxn matrices. But you can easily invent restrictions that makes it more interesting, such as requiring all numbers to be prime, or powers, or any other numerologically interesting property. You can also try many-dimensional magic squares. see http://mathworld.wolfram.com/topics/MagicSquares.html
- The Domino game: Given a game board consisting of a subset X of {0,...,n}^2, player 0 and 1 alternatingly remove two adjacent squares from X. (Equivalently, paint some squares of a chessboard red, then try to cover only red squares with domino bricks.) The player that gets stuck first (cannot move) loses.

Reading instructions for the written exam
See schedule
Prepare yourself by
- reading and understanding all material (textbook chapters and handouts)
- solving more exercises in the book
- refresh your memory of the book chapters covered by earlier courses. (Altogether, the AD1, AD2, and AD3, have covered chapters 1 - 18, 21 - 30, 32 - 34)
Examination
i. Written Exam
ii. Mandatory assignments
iii. Oral examination, each student will have an oral exam, after the written exam. At the oral exam, you must bring written solution (not handwritten, but nicely formatted)
solutions to at least half of the assignments.)
Rules for exam:
In addition to the normal stuff (pens, pencils, eraser, ruler and so forth), you should bring the textbook. At the exam, you will also be provided with a copy of sections 1-4 of "New bounds on sorting and searching".
