Space partitioning is needed in the situation where one needs to treat different parts of a combined system with different exchange-correlation functionals. For example, bulk and surface regions of a system could be treated with functionals that are specifically designed to capture the distinct physics of those regions. Here we use the space partitioning scheme to implement the quasi-nonuniform exchange-co","authors_text":"H. Lev\\\"am\\\"aki, K. Kokko, M.
