Crux seems to be &quot;our algorithm searches the full design space of fabricable devices with arbitrary topologies.&quot; Very useful, but may be not that spectacular, depending on the efficiency of that search.</p><p><a href="https://hackerpaper.kaipfister.de/p/1504.00095/">Paper and discussion history</a>.
