Best fit algorithm for bundling/grouping
I have a group of different products having different quantities and want to bundle them in to groups summing up to 10 as close as possible. For example, below I have 11 products and I want to break them in to groups that would have the sum of the quantity equal to or closest to 10. Has anyone tried something like this in Anaplan?
Product  Quantity 

Product 1:  2.15 
Product 2:  1.5 
Product 3:  3.2 
Product 4:  2 
Product 5:  0.4 
Product 6:  3 
Product 7:  1.8 
Product 8:  2.35 
Product 9:  2.75 
Product 10:  0.75 
Product 11:  0.1 
So an output for the above are 2 groups with the following groupings:
Group 1:  

Product 2:  1.5 
Product 4:  2 
Product 6:  3 
Product 9:  2.75 
Product 10:  0.75 
Total Group 1:  10 
Group 2:  
Product 3:  3.2 
Product 7:  1.8 
Product 8:  2.35 
Product 1:  2.15 
Product 5:  0.4 
Product 11:  0.1 
Total Group 2:  10

Hey, that looks interesting. Do you want to create groups automatically where the sum of products is 10?

Hi @TristanS
Insightful Question
We can think this mathematically as below.
Step1: Try to add previous list value to current value and then comapre Sum of it with next time addition of previous list value to current value
Lineitem1 : add previous list value to current value
Lineitem2 : if Lineitem1 Close to 10 and Next of Lineitem1 >10 then mark those product name
Lineitem 3: In this lineitem try to name each group with group1,group2 ……
It will create groups as below, but not as you have mentioned on the topProduct
Quantity
Product 1:
2.15
Group 1
Product 2:
1.5
Group 1
Product 3:
3.2
Group 1
Product 4:
2
Group 1
Product 5:
0.4
Group 1
Product 6:
3
Group2
Product 7:
1.8
Group2
Product 8:
2.35
Group2
Product 9:
2.75
Group2
Product 10:
0.75
Group2
Product 11:
0.1
Group2
Looking forward to see if this can be solved in any other way

Pujitha  a challenge here  With this way, starting all products when quantity < 10 will be grouped. But the bigger challenge might be to find all possible groups automatically.
That's what i am looking to clarify with Tristan and confirm.

All possible combinations of groups, right? Or is there a limit to how many groups you need?

@Dikshant No limit on number of groups. Rules are:
 A product must belong to a group and one group only
 The grouping should sum up to 10 or closest to 10
FYI: This is for optimising cargo load. E.g. a transport has a maximum capacity of 10 units so you want to fill up the transport to the maximum possible given amount of products requiring delivery.
I'm across recursive algorithms outside Anaplan but not quite sure Anaplan would be able to do it even though Anaplan supports some form of recursion via time dimension through previous and next function calls.

At my finance company we do something similar. We have a bunch of contracts that we must put into different funding vehicles. Each vehicle has a lot of different constraints such as 25% of contracts can't be in Florida or no more than 10% of contracts can be longer than 12 months. We use anaplan for this. I will have to get back to you on specifics. We can't possibly run all the possibilities (we have 1,000s of contracts everyday). So what we do is we have the model spit out 3 different scenarios and we pick the one we like best. Hope that helps
