having a large array of doubles,also and above all repeated, I would like to find a single combination of sums as short as possible, only with repeated numbers available
i.e. with fewer elements to add.
I simplify with an example with very few numbers:
5
5
5.1
5.1
5.1
5.1
5.4
5.4
5.4
6
6
6
6.5
6.5
8
10
10
15
40
40
60
60

I would like to find the shortest amount to get
30.4 -> 5.4 + 10 +15 Good
30.4-> 5.4 +5 + 5 +5 +10 BAD (not the combination of sums with fewer numbers)
or:
130-> 60 + 40 + 10 + 10 + 5 + 5 Good
130-> 60 + 40 + 10 + 10 + 10 Bad because I don't have 3 digits of 10 available
so
if I have the figure 10 repeated 3 times, I can only use it 3 times in the combination to reach the target

While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.

So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.

Difficult to tell what you want since as I understand:
130-> 60 + 60 + 10 Better solution
