# Help wih a Galapagos definition from scratch!

Hi Community!

I am very new to Galapagos and have recently discovered its vast potential for design optimisation. But I need your help!

I have a fundamental rectangular shape, where I want to make some windows. What I wish Galapagos to do is to make the best placement of the windows in terms of the sun (for heat gains) as well as for people to look inside the rectangle. It would be nice if I was able to also determine the minimum and maximum area of glass as well (for costs).

Does anyone have a good idea of how to do this?

Thanks in advance! <3

This is rather vague and broad. Perhaps the following will serve as a start. Above screenshot is a pseudo script meant to diagram the process.

I donâ€™t know how you want to create windows but presumably a bunch of sliders determine their shape and location. Like the four sliders in my screenshot. They made a smaller rectangle in the parent rectangle.

Then you have 3 criteria. Without going to multi-fitness solvers, youâ€™ll need to come up with your own weighed formula to â€śscoreâ€ť these criteria. I used meaningless fictitious numbers. However, I mocked up a glass area criterion (cost), a heat gain, and a view exposure.

I assumed the higher the heat gain the worse so that had a negative in the formula `-h`. Higher glass cost the worse so `-c`. Larger view score the better so `+v`, with a demonstrative yet meaningless multiplier `x2`. All to show that youâ€™d need something similar to this to be able to utilize Galapagos. Each of those purple groups represent possibly a much larger complex script, which defines how the values of cost, heat gain, or view vector/score are derived for your purposes.

You may already know all of this but again I think your request is very broad. One way to draw out the experts much more capable than me is to provide a bounty if you can afford.

@Will_Wang Thank you, I will check this out! Again, thanks for your time!
