New Room: MATH 202

Cookie recipe

Happy New Year. This course should be a lot of fun for students. It can be considered a capstone course, giving students an opportunity to use their mathematical maturity to work on `real world' problems. It is a Arts degree `research intensive approved course' which is a degree requirement for a B.A.

The course has a reasonable amount of work and certainly the project takes a lot of time but students typically enjoy the experience. Also there is no final exam! This course does have MATH 340 as a prerequisite. You can discuss with me if this is missing.

This course uses discrete optimization techniques such as Linear programming and Integer Programming. We will be using software (LINDO, LINGO) for assignments and possibly the project. The course is organized with 50% for assignments and 50% for a project. The project is done in a groups of at most 3 and a polished write up is expected. There is no final exam. Contact me if you have questions before selecting this course.

Computer Lab access.

The Course Outline gives a timeline for projects. It is important that groups and projects are chosen early. I will accept project proposals on Thursday Feb 6.

Projects

Melissa, Daniel and Shaun are tackling a diet problem. Canada Food Guide will figure prominently.

presentation Thursday Feb 27. First diet had many servings of carrots but ideas how to diversify the diet are being explored. Project handed in. They hope to give a presentation on Tuesday April 8.

Yuzhou, Jackie, William are seeing if the assessor's job can be done with some curve fitting.

presentation Thursday Mar 6. A target area of Shaugnessey was chosen. Errors less than 15% seem possible.

Alfred, Jonathan, Gary are looking at Markowitz Portfolio Model

presentation Tuesday Mar 4 with large datasets examined. They examined 32 stocks. Not a large selection of stocks are required to achieve diversity. Project handed in.

Colin, Alexander, Brian video game team analysis (Pikachu?)

presentation Thursday Mar 6. Simulation running well to determine which of two pokemon characters would win. 10,000 runs can determine useful data for a payoff matrix. Some good teams selected. A presentation on Tuesday April 8 may happen.

Timon, Tony, Jianwen car sales planning.

presentation Thursday Mar 6. A dealers ordering decisions explored by Network Flows (for deterministic slaes) and Dynamic Programming (for probabilistic sales). Some refinements should make this problem quite interesting. Project handed in.

Banghao Harley, Yi Hockey Team selection

presentation Thursday Feb 27. First team selection has been done! The group hopes to submit some teams to the CBC fantasy pool. Project handed in. Presentation on Tuesday April 8.

Ray, Jie, Xinyuan TA assignment but can 25x60 variables be handled?

presentation Tuesday Mar 4. Interesting data collection ideas. The first runs successfully schedule the TA's. Project handed in.

Chelsea, Carson, Clement Criminal Element (gangster). Initial solution obtained.

presentation Tuesday Mar 4. A larger problem of 45 wards was solved in 2.5 hours! They indicate that they might be able to present April 8.

Jacqueline, Doug, Xiaoyu are exploring the diet problem

presentation Tuesday Mar 4. A quite reasobable diet proposed that tries to balance time with preparation time. At least Doug doesn't like preparation time. Project handed in.

Some changes are possible but I wish the groups to begin exploring their project early. In particular, I would like a written report and verbal report on or before Thursday February 27. It is a chance for you to see how your group should be organized to produce a report and a chance to contemplate the scope of your project and the difficulties you might encounter. Consultation with me is essential. I can help you identify the questions that you might focus on and indicate parts of the project that are likely to be hopeless. It is your responsibility to make the project interesting for me. There is no `right' answer. You might find useful information in the handout Project Information.

Groups formed:

We will have about 15 minute group presentations as progress reports on Thursday February 27 and Tuesday March 4. Aim to have a nice overview of the problem (this will probably be useful later on when you are doing your write up) and give some sample input/output to indicate your progress to date. The final project is Due Tuesday April 1.

Grading this course can be a challenge. It is disconcerting for students that they won't get 100% for the correct answer. We give the top marks only to those with clear and interesting writeups. The average in the course will probably be in the low 70's. The overall grading distribution will be reminiscent of an Arts course. I expect many good results but only the occasional stellar writeup.

The notes look authoritative when typed so be wary. They may look perfect but may still contain errors! I don't have an editor.

I arrive most days by 9:00. I am also scheduled to teach 15:00-16:00 MWF. I typically do not read my email from home (i.e. evenings and weekends).
