    A.M. Turing Award Oral History Interview with Robert (Bob) Endre Tarjan by Roy Levin San Mateo, California July 12, 2017 Levin: My name is Roy Levin. Today is July 12th, 2017, and I’m in San Mateo, California at the home of Robert Tarjan, where I’ll be interviewing him for the ACM Turing Award Winners project. Good afternoon, Bob, and thanks for spending the time to talk to me today. Tarjan: You’re welcome. Levin: I’d like to start by talking about your early technical interests and where they came from. When do you first recall being interested in what we might call technical things? Tarjan: Well, the first thing I would say in that direction is my mom took me to the public library in Pomona, where I grew up, which opened up a huge world to me. I started reading science fiction books and stories. Originally, I wanted to be the first person on Mars, that was what I was thinking, and I got interested in astronomy, started reading a lot of science stuff. I got to junior high school and I had an amazing math teacher. His name was Mr. Wall. I had him two years, in the eighth and ninth grade. He was teaching the New Math to us before there was such a thing as “New Math.” He taught us Peano’s axioms and things like that. It was a wonderful thing for a kid like me who was really excited about science and mathematics and so on. The other thing that happened was I discovered Scientific American in the public library and started reading Martin Gardner’s columns on mathematical games and was completely fascinated.

  • The Best Nurturers in Computer Science Research
    The Best Nurturers in Computer Science Research Bharath Kumar M. Y. N. Srikant IISc-CSA-TR-2004-10 http://archive.csa.iisc.ernet.in/TR/2004/10/ Computer Science and Automation Indian Institute of Science, India October 2004 The Best Nurturers in Computer Science Research Bharath Kumar M.∗ Y. N. Srikant† Abstract The paper presents a heuristic for mining nurturers in temporally organized collaboration networks: people who facilitate the growth and success of the young ones. Specifically, this heuristic is applied to the computer science bibliographic data to find the best nurturers in computer science research. The measure of success is parameterized, and the paper demonstrates experiments and results with publication count and citations as success metrics. Rather than just the nurturer’s success, the heuristic captures the influence he has had in the indepen- dent success of the relatively young in the network. These results can hence be a useful resource to graduate students and post-doctoral can- didates. The heuristic is extended to accurately yield ranked nurturers inside a particular time period. Interestingly, there is a recognizable deviation between the rankings of the most successful researchers and the best nurturers, which although is obvious from a social perspective has not been statistically demonstrated. Keywords: Social Network Analysis, Bibliometrics, Temporal Data Mining. 1 Introduction Consider a student Arjun, who has finished his under-graduate degree in Computer Science, and is seeking a PhD degree followed by a successful career in Computer Science research. How does he choose his research advisor? He has the following options with him: 1. Look up the rankings of various universities [1], and apply to any “rea- sonably good” professor in any of the top universities.

  • Secure Fault-Tolerant Protocols and the Public-Key Model
    Cryptographic Computation: Secure Fault-Tolerant Protocols and the Public-Key Model (Extended Abstract) Zvi Galil'. 2* Stuart Habedl Moti Yung'r 3*4 Department of Computer Science, Columbia University Department of Computer Science, Tei Aviv University We give a general procedure for designing correct, secure, and fault-tolerant cryptographic protocols for many parties, thus enlarging the domain of tasks that can be performed efficiently by cryptographic means. We model the most general sort of feasible adversarial behavior, and describe fault-recovery procedures that can tolerate it. Our constructions minimize the use of cryptographic resources. By applying the complexity-theoretic approach to knowledge, we are able to measure and control the computational knowledge released to the various users, as well as its temporal availability. Supported in part by NSF grants MCS-8303139 and DCR-8511713. Supported in part by an IBM graduate fellowship. C. Pomerance (Ed.): Advances in Cryptology - CRYPT0 '87, LNCS 293, pp. 135-155, 1988. 0 Springer-Verlag Berlin Heidelberg 1988 136 s-rg An important area of research in cryptography is the design of protocols for cawing on certain uansactions in a communications network, such as playing poker or holding an election. Many of the pr~tocolsproposed in this area have required the expensive on-line generation of a large number of new keys. On the other hand, fundamental research in the traditional problems of cryptography, such as encryption and authentication, has developed the public-key model, in which each user has a single validated public key. This model is appropriate to those situations in which generation and validation of new keys is very costly or is othewise limited.

Each update to the graph is either an edge deletion or an edge insertion. We give the first data structure that simultaneously achieves a constant approximation factor and handles a sequence of k updates in k polylog(n) time. Previous data structures require a polynomial amount of computation per update.· The starting point of our construction is a distributed algorithm of Parnas and Ron (Theor. Comput. Sci. 2007), which they designed for their sublinear-time approximation algorithm for the vertex cover size. This leads us to wonder whether there are other connections between sublinear algorithms and dynamic data structures. 1 Introduction Suppose one is given the task of solving a combinatorial problem, such as maximum matching or minimum vertex cover, for a very large and constantly changing graph.

The Conference offers leaders timely and authoritative assessments and policy recommendations needed to guide their organizations through the challenging geopolitical, economic and social developments. Harnessing path-breaking methodologies, the Conference’s task force reports and the commissioned studies present an accurate, coherent, continuous and comprehensive picture of the region and the world. Strategic and political processes and events emanating from an ever-turbulent Middle East increasingly impact the global arena. Shaping the regional and international policy debates and directly influencing decision-making, the deliberations at Herzliya cover a broad span of issues, ranging from nuclear proliferation and the Middle East peace process to world finance, energy security and global warming.

  • Minimum-Knowledge Interactive Proofs for Decision Problems*
    SIAM J. COMPUT. (C) 1989 Society for Industrial and Applied Mathematics Vol. 18, No. 4, pp. 711-739, August 1989 0O6 MINIMUM-KNOWLEDGE INTERACTIVE PROOFS FOR DECISION PROBLEMS* ZVI GALIL'?, STUART HABER$, AND MOTI YUNG Abstract. Interactive communication of knowledge from the point of view of resource-bounded compu- tational complexity is studied. Extending the work of Goldwasser, Micali, and Rackoff [Proc. 17th Annual ACM Symposium on the Theory of Computing, 1985, pp. 291-304; SIAM J. Comput., 18 (1989), pp. 186-208], the authors define a protocol transferring the result of any fixed computation to be minimum-knowledge if it communicates no additional knowledge to the recipient besides the intended computational result. It is proved that such protocols may be combined in a natural way so as to build more complex protocols. A protocol is introduced for two parties, a prover and a verifier, with the following properties: (1) Following the protocol, the prover gives to the verifier a proof of the value, 0 or 1, of a particular Boolean predicate, which is (assumed to be) hard for the verifier to compute. Such a deciding "interactive proof-system" extends the interactive proof-systems of [op. cit.], which are used only to confirm that a certain predicate has value 1. (2) The protocol is minimum-knowledge. (3) The protocol is result-indistinguishable: an eavesdropper, overhearing an execution of the protocol, does not learn the value of the predicate that is proved. The value of the predicate is a cryptographically secure bit, shared by the two parties to the protocol. This security is achieved without the use of encryption functions, all messages being sent in the clear.
