This works really awesome..... some of the code a bit over my head so I'm trying to break it down and understand all the pieces. Couple questions:

1) the 'our' declaration - I read about the definition and usage but still don't really understand why you use it here instead of ''my'?

2) to make sure I understood your code and the process, I set out to solve the problem if we want to minimize the number of nozzles per machine rather than minimize the number of machines. In other words we would want to minimize the average chemical per machine. How would you alter your code above to accomplish this?

3) I get a bit lost when you get to the 'splice' and 'delete' lines of your code... I follow that you want to use splice on the HoHoA because after you assign the flow you want to remove it from consideration...but what is the delete part serving to do?

4) do you have a good book recommendation or online exercises recommendation on these types of dynamic programming? The only language I know (barely) is perl...

thanks again for your help... it's made huge difference in my learning!
