Well, what are you trying to do in the first place? It'd be a lot more helpful if we knew the reason behind what the code actually does.
EDIT: And well, line 53 just sets each element to "Random", I'm not sure if that got cut off while pasting, but, that definitely doesn't make sense.

The arrays obs[] and ref[] are each 10 elements long, with obs[] representing the 10 different readings taken on a given day in the plant. Now, the values of the 10 elements in obs[] change every day of the five-day week but for a given week, the ref[] values are the same. These can be thought of fixed values to be adhered to for a whole week, but the fixed values are different for different weeks. The goal is to find the total deviation for a given week.
