What is it about?
We introduce a new way of designing patchy colloidal particle interactions such that specific polyhedral shells are formed, while avoiding competing structures. This is done by casting the assembly process as a boolean satisfiability problem (SAT). We also provide general rules that can guide the system towards more successful assemblies.

Why is it important?
At the micro scale, thermal fluctuations can drive the self-assembly of colloidal particles into polyhedral shells. On the other hand, the assembly process can be blocked by the formation of irregular clusters that are much different from the one preferred. We introduce a new mechanism that allows us to automatically design how particles interact such that these irregular clusters are avoided. Thus, leading to a more predictable assembly process.
