I wrote this explanation of how to calculate probabilities like the ones you estimated in the last homework.December 8, 2015
Here is a histogram of the scores from Homework 5.

With the c++ program below, the output can be sent to a csv file. When read into R with a command of the form
r1 <- read.csv(file.choose(new=FALSE),head=FALSE,sep=",")
you can then make plots of all the estimated probabilities with this R command sequence:
plot(r1$V1,r1$V2,type="o",ylim=c(0,0.6),pch=NA,ylab="probability",xlab="simulated hours")
par(new=T)
plot(r1$V1,r1$V3,type="o",ylim=c(0,0.6),pch=NA,ylab="probability",xlab="simulated hours")
par(new=T)
plot(r1$V1,r1$V4,type="o",ylim=c(0,0.6),pch=NA,ylab="probability",xlab="simulated hours")
par(new=T)
plot(r1$V1,r1$V5,type="o",ylim=c(0,0.6),pch=NA,ylab="probability",xlab="simulated hours")
par(new=T)
plot(r1$V1,r1$V6,type="o",ylim=c(0,0.6),pch=NA,ylab="probability",xlab="simulated hours")

Here are the files I used for the Tour de France MDS example:
If you copy all the files to your machine and run the script doit.txt from inside R, you'll get the plot shown in class. Note that I used the wordcloud library, so you'll need to install that first.November 12, 2015

- November 2: Groups A7, A10, A6, A9
- November 4: Groups A8, A5, A1
- November 6: Groups A3, A4, A2
Groups will present in the order listed. If time runs out, groups will be moved to the next presentation day, maintaining the overall order.

Here is an example of a worked LP problem to give you some idea of what your work should look like. Please also read the homework guidelines.

We'll be talking about these examples in class this week.

I have added a (partial) homework assignment. Check out the homework assignments link to the right.
I have also added a set of homework guidelines and suggestions. PLease read it through before starting to write up any homework.

Welcome to Math 381 A, Autumn Quarter 2015.
The course discussion board is availble (link at right). Please take advantage of it to ask questions about homework problems or course topics. You might also use it as a way to arrange study groups. I will get immediate emails when posts are added to the board, so this is as good a way to contact me as email, but allows everyone to see my response.
For those students looking for an add code, I do not overload my courses. If there are opening in the first week, you can add yourself to the course. No adds will be allowed after one week. There are no add codes.
The first homework assignment will be posted soon.
