Computer Science Assistant Professor Lewis Tseng wins Best Paper Award at SSS 2017

Computer Science Assistant Professor Lewis Tseng has earned the Best Paper Award at the 19th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS 2017), for his paper entitled An Improved Approximate Agreement Algorithm in the Presence of Mobile Byzantine Faults. SSS was held in Boston, Nov. 5-8, 2017.

The paper explores "the problem of reaching approximate consensus in synchronous point-to-point networks, where each pair of nodes is able to communicate with each other directly and reliably." It proposes "a novel technique of using 'confession' (a mechanism to allow other nodes to ignore past behavior) and a variant of reliable broadcast to improve the fault-tolerance level."
