& grading
Quiz (q1). Problem 1: Most of students got the answer:
x=53, y =  37.
Problem 2: Most of students got x=b/a which works
only for nonzero a. 2 pts were given for this.
The best score was 4 pts. The problem is solved in the class
notes. Similar problems will
be given again and again until most of students learn to avoid division
by 0.
Jan 9 class. q2: Both 0=0 and 0=1 are linear constraints. Moreover,
they are the most important
linear equations.
Jan 16. q3: min=72 at x=0, y=9. The feasable region
is a hexagon.
Jan 18. 0=1 is a linear equation with no solutions.
F Febr 1: § 9. Homework 3 collected, 20 pts.
M Febr 4: § 10.
W Febr 6: midterm 1, 50 points, covers ch. 13.
pictures.
M Feb. 18. h5 (solve your diet problem) due, 30 pts.
F Febr 22. q5, In Ex.7, the "solution" does
not satisfy any of 3 constraints in the tableau.
In Ex.810, the solution is feasible.
The solutions in Ex.7,8, 10 cannot be optimal because the values
for the objective function, 13,2,3 are greater
than the value 1 in Ex. 9.
The solution in Ex.9 is optimal, because 1 is a feasible value
for
the dual problem: y6=1,y7=2,y8=1, all other y's = 0,
where y_{i }corresponds to x_{i}.

the two problems from q8,
15 pts for each problem.

Internet humor
So I spend 2 weeks collecting data to show that it is
linear, and it turns
out to be certainly NOT linear and most definitely
parabolic, so I call a
meeting of the hardware people to discuss options
for fixing the hardware so
that my data does come out linear, and the solotion
was: Ignore the data on the right side of the parabola.
Then the data on the left side looks almost linear.
Problem solved!
