Ever go to the races with mom and dad? Marriage and the family, sickness and health, travel and the car, fun and games -- these are the key features of Jiddo's life.

Inferring gene regulatory networks is a difficult problem to solve due to the relative scarcity of data compared to the potential size of the networks. While researchers have developed techniques to find some of the underlying network structure, there is still no one-size-fits-all algorithm for every data set. Network Inference in Molecular Biology examines the current techniques used by researchers, and provides key insights into which algo...

Excerpt from Optimal Best-Match Retrieval The best-match problem (also known as the post office problem or the nearest neighbor problem arises in many applications, such as database management information retrieval [4, 7, molecular biology [15, pattern classification [11, 14, 18] and computational geometry The problem is to find, among a file of objects, the ones which are most similar or closest to a given target according to some similarity...

Excerpt from Query Processing in a Symmetric Parallel Environment We consider a database machine consisting of n nodes connected by an O(n processing speed) bandwidth network. Each node consists of a processor, a random access memory, and a slower but much larger memory such as a disk. In order to approach optimal (O(n))speedup on this hardware architecture, we partition relations roughly evenly among the processors. We study the problem of o...

Excerpt from Join Processing in a Symmetric Parallel Environment We present and analyze a strategy for procuring joins on a highly parallel computer architecture. We model the architecture as consisting of n identical processor-meraory clusters interconnected by a symmetric network onto which many processors may send at once. The strategy entails partitioning each relation horizontally based on a perfect hashing function applied to a key of t...

Excerpt from Efficient and Correct Execution of Parallel Programs That Share Memory In this paper, we consider an optimization problem that arises in the execution of parallel programs on shared memory multiple-instruction stream multiple-data stream (MIMD) computers. A program on such a machine consists of many program segments each executed sequentially by a single processor. The processors have access to shared memory, and can execute stan...

Excerpt from When Does Non-Linear Text Help?Now, suppose you sit down for a night of reading short stories. You may not want to read them in the order specified by the table of contents, but you are likely to read any story you choose in the order it is written. In this case, a non-linear text system provides no benefit over linear text. There is no need for more than one arrangement.These examples illustrate that the need for a non-linear tex...

Collected and enhanced from Dennis Shasha's popular Scientific American column, here are thirty-five of the most innovative and emotive mathematical puzzles ever to appear in its pages. Edgy, challenging and representing the ultimate in recreational mathematical games, Puzzling Adventures dares the reader to work out the logic underlying venture fund investments, escape a Minotaur, catch a polar bear, play power politics, work out if a witness...

Computers built from DNA, bacteria, or foam. Robots that fix themselves on Mars. Bridges that report when they are aging. This is the bizarre and fascinating world of Natural Computing. Computer scientist and Scientific American's "Puzzling Adventures" columnist Dennis Shasha here teams up with journalist Cathy Lazere to explore the outer reaches of computing. Drawing on interviews with fifteen leading scientists, the authors present an unexpe...
