this sounds amazing! aside from the organics-only requirement (which makes sense to me), what other limitations are there on what you can make? or is everything basically open given a long enough search?
Most of the time changes do nothing! But if our models are accurate enough, the engineering can be predictable. We are continuously improving our models -- from more data mining, and from feedback from experiments.
That said, what our algorithm predicts right now is still a huge space (5000-10000 products). That is the tree image in the article. For context, the chemical industry centers around 70,000 products.
