| Three negative results: 1. Given a set of allowed starting materials and allowed chemical reactions, the problem of determining whether a chemical of speciied structure is synthesizable is Turing undecidable. 2. The question of whether it is synthesizable in N steps is NP-hard. These results apply in a general abstract setting and do not prove anything about how hard the problem is with any s...
