Vijay Virkumar Vazirani ((ヒンディー語:विजय वीरकुमार वज़ीरानी); b. 1957〔(Deutsche Nationalbibliothek'' )〕) is an Indian American Professor of Computer Science at Georgia Tech.〔(Faculty page at Georgia Tech )〕 He received his Bachelor's degree from MIT in 1979 and his Ph.D. from the University of California, Berkeley in 1983. During the early to mid nineties, he was a Professor of Computer Science at the Indian Institute of Technology, Delhi. Vijay Vazirani was also a McKay Visiting Professor at the University of California, Berkeley, and a Distinguished SISL Visitor at the Social and Information Sciences Laboratory at the California Institute of Technology. ==Career== His research career has been centered around the design of algorithms, together with work on computational complexity theory, cryptography, and algorithmic game theory. During the 1980s, he made seminal contributions to the classical maximum matching problem,〔Three of his papers on the subject from that time period have over 100 citations each, according to Google scholar: ; ; .〕 and some key contributions to computational complexity theory, e.g., the Valiant-Vazirani theorem. During the 1990s he worked mostly on approximation algorithms, championing the primal-dual schema, which he applied to problems arising in network design, facility location and web caching, and clustering. In July 2001 he published what is widely regarded as the definitive book on approximation algorithms (Springer-Verlag, Berlin). Since 2002, he has been at the forefront of the effort to understand the computability of market equilibria, with an extensive body of work on the topic. Two of his most significant research results were proving, along with Leslie Valiant, that if UNIQUE-SAT is in P, then NP = RP (Valiant–Vazirani theorem), and obtaining in 1980, along with Silvio Micali, an algorithm for finding maximum matchings in general graphs; the latter is still the most efficient known algorithm for the problem. He is the brother of UC Berkeley computer science professor Umesh Vazirani. In 2005 they both were inducted as Fellows of the Association for Computing Machinery.〔(ACM Fellows Award: Umesh Vazirani ).〕〔(ACM Fellows Award: Vijay Vazirani ).〕 In 2011, he was awarded a Guggenheim Fellowship. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Vijay Vazirani」の詳細全文を読む スポンサード リンク
