solution (xls).

2nd lab: Exercise,
AMPL model,
dat file,
run file.
Exercise 2.

3rd lab: Continuing exercise 2,
AMPL model,
data file,
run file.
Exercise for Sensitivity Analysis,
AMPL model,
data,
run file.

4th lab: Exercise,
NEOS server,
Exercise 2,
GAMS model, about the XPRESS Optimizer

5th lab: Finish the last exercise, and solve
this one

6th lab: Check the LP formats (simple, CPLEX LP) and MPS format (intro,
other), and try to write AMPL or GAMS model for the 8 queen problem, or this one.

For the solution, write the mathemtical model, solve it with Excel, and analyse the result using the sensitivity and other reports of Excel (see this as an example). Send the solution in an email, the mathematical model and the analysis can be in the letter or written in an Excel sheet.

The homeworks will be evaluated, and it will be taken into account for the final grade.
