[R] New R user- Simple optimization problem

[Bert Gunter]

Homework?

If so, we don't do hw here. Otherwise, we usually ask people to show us
their failed coding efforts rather than expecting us to do the problem for
them. Please read and follow the posting guide.

Cheers,

Bert

Hi I am learning R currently and I having trouble structuring a program.



Data consists of 1 data frame with a day of the week, a class list, and a
utility score.



Date                   Class                   Utility



Monday              Chem                  85

Monday              Physics               75

Tuesday              Chem                  95

Tuesday              Math                  93

Tuesday              History               87

Tuesday              Language           86



And so on through Friday.



I want to maximize total utility (the sum) given 2 constraints:



1.      The number of classes you must take each day is fixed. (Must take 1
class on Monday, 2 on Tuesday, 1 on Wednesday etc.)
2.      No repeats- You can only take any given class zero or one time.



Any help to go about this would be appreciated.



Thank you.
