Distributing within given parameters

Hello.

First of all i must say im a quite newbie user of Grasshopper, Rabbit and Galapagos; so maybe i tried things in my files that could have been made easier or smarter. Sorry for that. Maybe what im trying is not possible. I cant found the way to do it. But you clearly know much more than me so i should give it a try :D

Secondly, Im not english speaker so maybe I do a lot of mistakes, sorry in advance, i will clarify in comments whatever i cant explain good enough.

Im doing urban design, i want to distribute random functions over my designed sprawl. But i dont want to do it randomly. I first tried to do it with percentages, but that was not as accurate as i wanted. I designed some parameters which i want to have in mind while doing it. Because it is a big file and have a lot of parameters i have simplified it to a house, in a file which i attach. 

In this "house" i want to distribute the rooms in some given boxes, but having in mind the "optimal relation" between rooms, in height and with the main road.

In the diagram i have write the relations between rooms, in this way, is better to have kitchen and livingroom together and is worst to have sleeping room and kitchend together. In the same way is better if rooms are on a higher floor and far from the road.

I set some gradients for these parameters -not between different uses, i dont know how- but now i wanted to find the better way to fit these "rules".

I think that Galapagos would help me do it, but i dont know how to use it in this way either.

i hope you could help me. And i wish i explained well myself.

Thank you so much for reading and for helping.
