CS Colloq: Mechanism Design and Analysis Using Simulation-Based Game Models
Mon, Mar 10, 2008 @ 11:00 AM - 12:00 PM

Title: Mechanism Design and Analysis Using Simulation-Based Game ModelsSpeaker: Yevgeniy Vorobeychik (UMICH)Abstract:
I present a general framework for automated mechanism design on constrained design spaces when the outcomes of strategic interactions between the mechanism designer and participants are specified using a simulation. At the core of the framework lies a black-box stochastic optimization algorithm which guides the selection process of candidate mechanisms. I demonstrate the efficacy of such an approach using a series of applications to two-player design problems. A critical component of mechanism design based on simulations is an algorithm for approximately solving simulation- based games. I present several such algorithms, one of which is provably convergent, and experimentally assess their relative merits.Biography:
Yevgeniy Vorobeychik is a Ph.D. candidate at the University of Michigan AI Laboratory. He has been a fellow in the STIET (Socio-Technical Infrastructure for Electronic Transactions) program for two years and has received honorable mention in the Computer Science & Engineer honors competition for his work on simulation-based mechanism design. His research interests include electronic commerce, game theory, mechanism design, multi-agent systems, and artificial intelligence.Location: Vivian Hall of Engineering (VHE) - 217

“Brillouin Scattering Slow Light in Fibers, and Secure Optical Key Generationâ€
Mon, Mar 10, 2008 @ 02:00 PM - 03:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
SPEAKER: Dr. Avi Zadok, Post-doctoral Scholar, CalTechABSTRACT: Stimulated Brillouin Scattering (SBS) is a non-linear propagation effect which couples between a strong pump wave and a typically weak probe wave in an optical fiber. The gain process experienced by the probe wave is accompanied by a controllable group delay. In recent years, SBS has been widely used for the variable delay of high-rate data streams (slow and fast light), for a potential application of optical buffers [1]. In the first half of the talk, several less-known aspects of SBS-based slow light, which could lead to a broader range of applications, will be demonstrated. First, the maximum usable delay may be extended through careful optimization of the pump wave modulation, and control of its spectrum. Second, SBS can be applied to process and delay analog waveforms. Such processing is highly attractive, for example, in optical beam-forming in broadband, phased array antennas [2]. Finally, SBS is strongly dependent on polarization and fiber birefringence. This dependence may be used for locking and synthesis of the output probe state of polarization.
The second half of the talk will be dedicated to a novel protocol for secure key generation in the optical domain. The proposed scheme is based on establishing Ultra-long Fiber Laser (UFL) oscillations along a link between two users [3]. The key bits in the UFL system are represented by the choices of spectrally-selective mirrors made by the two users. While these choices can be simply determined by the legitimate end users, they may not be reconstructed by an eavesdropper employing either time or frequency domain attacks. Unlike quantum key distribution protocols, the UFL system consists entirely of standard, off-the-shelf fiber-optic components. The system allows for the use of amplifiers, and its bit rate decreases only linearly with distance. Experimental results demonstrating secure code generation will be presented.[1] Z. Zhu et al., J.
