个人简介
Collaboration with Gagan Choudhury began in 1992 when he spent a year as an intern in the Mathematics of Networks and Systems Department (headed by Debasis Mitra, where I was) in the Mathematical Sciences Research Center at Bell Labs. As a member of the Network Design and Performance Analysis Department (headed by Pat Wirth), Gagan had already established a strong interest in algorithms and performance analysis tools. Thus Gagan was an ideal person to partner with Joe Abate and me in our efforts to develop numerical transform inversion tools.
Gagan is especially attracted to hard problems. Thus he was attracted to the challenging multidimensional numerical transform inversion problems. Indeed, Gagan wrote almost all the multidimensional inversion code. In doing so, Gagan demonstrated extraordinary algorithm and programming skills as well as mastery of the underlying theory. The basic multidimensional numerical transform inversion algorithms are not so difficult (when the dimension is not large), as can be seen from our 1994 Annals of Applied Probability paper. The real difficulty usually lies in developing special methods to treat specific problems. The challenge, and Gagan's great contribution, can be seen by looking at the 1995 J. ACM paper on closed queueing networks, the 1995 ToN paper on stochastic loss networks with state-dependent rates, the 1996 Performance Evaluation paper on polling systems and the 1997 Operations Research paper on the MtGt/1 queue (all appearing below). The algorithms in those papers go well beyond a direct application of the multidimensional inversion algorithm.
In addition to his important direct personal contributions, Gagan also has helped expand the numerical-inversion project by helping to enlist the cooperation of outstanding colleagues from his department such as David Lucantoni and Kin Leung. Gagan also contributed greatly to technology transfer within AT&T by leading the development of the "Q-squared" numerical-inversion-based performance analysis tool in his department.
