# Cubicle Adjacency Study by Optimo - Need Help with the Fitness Function

Hi,
I’m experimenting with Optimo nowadays and trying to achieve a task I planned months ago from this thread. My plan is to set an adjacency study for the cubicles in an office.

I tried Vikram’s graph before and there, rooms are organized according to the area and adjacency rates they have. In my case, I need cubicles to have a distance between them by the adjacency requirements I define in an Excel file.

So what I basically am trying to do is to find the optimal layout with the cubicles whom adjacency relation is produced by MS Project/Excel.

Then I created dimensional properties for these cubicles which are arbitrary numbers:
Cubicle List.xlsx (8.9 KB)
I first created cubicles and placed them on random coordinate points.

Then, I created a set of rules in a custom node which determines the distances between the cubicles(fitness function) and this fitness function is connected to the nodes of Optimo which should create a loop that will eventually let the system propose a new layout for me. This is my initial thought but I couldn’t make it work.

And here is my Dynamo file and the custom node of fitness function which I believe is problematic:

Total graph:

My fitness function:

How can I fix the fitness function, any thoughts on this would be highly appreciated.

I couldn’t create an adjacency rate from MS Project or Excel, so in order to represent a fictional distance between these cubicles, manually I put values multiples of 10 in Excel such as:

I wrote these values of distances for the cubicle pairs as a matrice in excel file “Adjacency Rates” It has two sheets.

PS: .dyf file gets very complicated at the end, I couldn’t manage a clean list.

Hi,

Very interesting, unfortunately I don’t have time to go through all of your stuff, I just thought you might find it easier to manage your input parameters (fitness function) if you did something like in this thread?

Hope that’s of interest,

Mark hi,
I’m super sorry for my late response but I was far from all of my electronic devices in the meantime. You are right that I should simplify the graph. But data is more accessible for me when it looks like a spirograph :))
But I gave another chance to this graph today with a different attempt. I simplified the process by just 3 cuboids. I couldn’t do it, yet it looks super simple so maybe someone can help me with that. In this basic example, I want to have 3 cuboids located randomly according to the rule of being close together.

And the fitness function is like:

It warns me in the yellow bubble as:
Warning: NSGA_II.AssignFitnessFuncResults operation failed.
Index was out of range. Must be non-negative and less than the size of the collection.
Do you know what might have caused this?
