In this paper, we present a prototype RD chip implementing a chemical RD processor for a well-known NP-complete problem of computational geometry \u2014 computation of a Voronoi diagram. We offer experimental results for fabricated RD chips and compare the accuracy of information processing in silicon analogs of RD processors and their experimental \"wetware\" prototypes. <\/jats:p>","DOI":"10.1142\/s0218127405013903","type":"journal-article","created":{"date-parts":[[2005,12,22]],"date-time":"2005-12-22T05:26:18Z","timestamp":1135229178000},"page":"3307-3320","source":"Crossref","is-referenced-by-count":15,"title":["SILICON IMPLEMENTATION OF A CHEMICAL REACTION\u2013DIFFUSION PROCESSOR FOR COMPUTATION OF VORONOI DIAGRAM"],"prefix":"10.1142","volume":"15","author":[{"given":"TETSUYA","family":"ASAI","sequence":"first","affiliation":[{"name":"Graduate School of Information Science and Technology, Hokkaido University, Kita 14, Nishi 9, Sapporo 060-0814, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BEN DE LACY","family":"COSTELLO","sequence":"additional","affiliation":[{"name":"Faculty of Applied Sciences, University of the West of England, Bristol BS16 1QY, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"ANDREW","family":"ADAMATZKY","sequence":"additional","affiliation":[{"name":"Faculty of Computing, Engineering and Mathematical Sciences, University of the West of England, Bristol BS16 1QY, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","first-page":"635","volume":"6","author":"Adamatzky A.","journal-title":"Neural Netw.
