Research highlights
(In reversed chronological order)
- Founder of the field of (linear) network coding; The paper "Linear network coding," mainly by Li, won the 2005 IEEE Information Theory Society Paper Award.
- The book "Algebraic Switching Theory and Broadband Applications" (2000-01) accumulates Li's original research findings on switching during 1985-2000 and transforms the electromechanical field into a new branch of applied algebra. A partial offspring of algebraic switching theory is fiber memory for optical data.
- Martingale of patterns in Li’s 1980 paper in Annals of Probability has been extensively cited by Ross’ textbook "Stochastic processes" and other books. The math technique in it has been actively applied to genetics, communications, and probability theory till now.

Note: These two papers were published before I consented. Part I was mainly just my work on network coding (NC) theory, including the Butterfly Network. Part II was a parallel nonlinear theory of network information flow, which is arguably another theory of network coding but totally different from NC in terms of problem formulation, angle of viewpoint, math tool, implementability, & usefulness
Note: This paper wins the 2005 IEEE Information Theory Society Paper Award. It initiates the study of network coding with linear coding mechanisms, which proves to achieve the best possible effect of network coding. This work is instrumental in popularizing network coding. The paper was mainly just my work, while the co-authors contributed greatly on the writing. A preliminary version appears in proceedings of the conference ISORA'98, pp. 197-211.
Note: The theory of "network information flow" is totally different from what the world regards as NC in terms of problem formulation, angle of viewpoint, math tool, implementability, & usefulness. However, how much this theory is related to NC became murky because it borrowed the Butterfly Network from NC and or published before the (linear) NC theory.
Abs: Because of the multi-user collision, the throughput of access protocols of local-area networks is typically low with respect to the channel capacity. From a new approach of dynamic coding, a media-access protocol is constructed for multiple parallel channels that guarantees at least 100% efficiency.
Abs: This paper pioneers in the study of periodic traffic in broadband ISDN. The necessary and sufficient speed of a packet switch based on a self-route interconnection network is determined for avoiding the phenomenon of persistent blocking due to output contention among periodic Streams of packets.
Abs: Based upon stochastic exchangeability, the computation speed of type of dynamic programming can be improved exponentially. Besides application to bin packing and random drawing of patterns, the application to casino blackjack is the only known technique for computing the exact odds of the game with today's computers.
Abs: A special job in an M/G/1 queue can not be served if it reaches the server before an exponentially timed event occurs, such as a parallel job, an answer from a remote data base, an operating environmental change, etc. While in the queue, there is always the option of moving the special job to the back of the queue. It is proved that, if the queue is stable, then it is optimal never to voluntarily elect the option.
Abs: A theory on binary trees is derived for analyzing the optimal smoothing of traffic cutback in data communication. Results are used in the volume control of CCIS queries of AT&T Calling Card Service. As a theoretic by-product, a close-form formula counts `l' bits in the binary representation of the first N integers.
Abs: Fermat's Little Theorem is applied to the construction of fast division routines. Software applications to the Traffic Services Position System saved the Bell System $49M (by the calculation of Dr. J. T. Gruenwald, the Bell Labs manager in charge). The application also settled a long-term dispute between Bell Labs and Southern Bell in a win-win.
Abs: This paper characterizes the ideal generators for a family of linear varieties. A corollary generalizes Turan's theorem relating the clique number of a graph to the number of edges. This paper is cited by Handbook of Combinatorics,. edited by Graham, Grotschel and Lovasz, 1995.
Abs: This paper invents a martingale technique for the study of occurrence of sequence patterns. With a transparent proof, a general theorem computes the waiting time till the occurrence of any pattern in a given collection and also computes the probability for each pattern to be the first to appear. This result, when restricted to the Bernoulli process, unifies some well-known formulas of William Feller and the leading-number algorithm of John Conway. This martingale technique is widely applied in genetics where each pattern represents certain sequential events of DNA mutation. This technique and the main theorems are all cited in the martingale section of Sheldon Ross.s textbook .Stochastic Processes..
Note: This paper is cited by "Handbook of Combinatorics" of Graham, Grotschel and Lovasz, 1995.
Note: This paper is cited by the book .Winning Ways. of Berlekamp, Conway and Guy, 1982.
Abs: Conway numbers give a complete theory on the class of perfect-information, finite-move Zugzwang games (Zugzwang means that it is a disadvantage to move.) This paper formulates the general perfect-information Zugzwang games with possible loops and derives the additive theory. The structure of Zugzwang games turns out to be isomorphic to the diadic rational points on a half plane with finite-move games corresponding to diagonal line on the boundary. This theory is cited by the book .Winning Ways. of Berlekamp, Conway and Guy, 1982.
Abs: A polynomial-time algorithm determines whether an integer sequence is the valence sequence of a unique graph up to isomorphisms.
Abs: With supply and demand located at points on a circle or a line, a linear-time algorithm yields the maximum matching with the smallest total distance of transportation. This is a paper in computational geometry before the term .computational geometry. becomes widely used.

Note: This monograph was submitted for publication before there was agreement on the sequencing of co-authors for the main part, which was called Part I.
Note: The bulk of research findings of Bob Li during 1986-2000 is published through this book, which attempts to establish switching theory as a new branch of applied algebra. Following are examples of original and industrial contributions of the book.
(1) The concept of preservation of conditionally nonblocking switches under certain versions of 2-stage interconnection is introduced. The preservation theorems enable flexible recursive constructions of large switches. Sporadic discoveries in the previous literature often are instances of special cases of a preservation theorem disguised under different languages. A preservation theorem pinpoints the intrinsic issue, avoids the confusion of ad hoc settings, enhances the depth of understanding, unifies sporadic discoveries, and offers the flexibility needed in real applications.
(2) Often interstage exchanges in a multistage interconnection network (MIN) are induced by permutations of address bits. The trace/guide transform is a powerful algebraic analog to the Fourier/Laplace transform of functions. It converts a MIN into an integer sequence, which characterizes various attributes of the network including routability, routing control, network equivalence under intrastage rearrangement, and preservation of assorted conditionally nonblocking properties of switches.
(3) The switching/router industry has always relied on either the crossbar or the memory switch fabric, both having reached their limits of upscaling. To this problem, Bob.s algebraic switching theory provides a theoretically sophisticated but hardware compact solution, which is now called the algebraic switch fabric. In recent years, ITRI, a renowned semi-Taiwanese-governmental organization undertook the .Metro Switch. project and adopted the algebraic switch fabric. This futuristic technology will be transferred to manufacturers upon the next upturn of the industry.

Note: The spirit of NC theory is to take advantage of joint coding among different pieces of data that are being transmitted on overlapping routes. Like the Patterson-Gibson-Katz paper on RAID in 1988, this paper was an application of NC before the NC theory.
