Dr. Alan J Hoffman is a pioneer in linear programming, combinatorial optimization, and the study of graph spectra. In his principal research interests, which include the fields of linear inequalities, combinatorics, and matrix theory, he and his collaboratorics, and matrix theory, he and his collaborators have contributed fundamental concepts and theorems, amany of which bear their names. This volume of Dr. Hoffman's selected papers is divided into seven sections: geometry; combinatorics; matrix inequalities and eigenvalues; linear inequalities and linear programming; combinatorial optimization; greedy algorithms; graph spectra. Dr. Hoffman has supplied background commentary and anecdotal remarks for each of the selected papers. He has also provided autobiogrphical notes showing how he chose mathematics as his profession, and the influences and motivations which shaped his career. Contents: The Variation of the Spectrum of a Normal Matrix (with H W Wielandt); Integral Boundary Points of ConvexPolyhedra (with J Kruskal); On Moore Graphs with Diameters 2 and 3 (with R Singleton); Cycling in the Simplex Algorithm; On Approximate Solutions of Systems of Linear Inequalities; On the Polynomial of a Graph; Some Recent Applications of the Theory of Linear Inequalities of Extrenal Combinatorial Analysis; and 37 other papers. Readership: Researchers in linear programming and inequalities, combinatorics, combinatorial optimization, graph theory, matrix theory and operations research.

Since the coming of the talkies, the thriller has been the film-goer's favourite genre - world-wide. This guide to 500 best English language thrillers contains a brief plot summary of each film, and contemporary and later reviews. A star-rating system to assess each movie at a glance is provided. Movies by Alfred Hitchcock, John Huston, Martin Scorsese, Steven Spielberg and Francis Ford Coppola, and performances by James Cagney, Cary Grant, Grace Kelly, Uma Thurman, Brad Pitt and John Travolta are included. The author adds his often controversial views.
They challenge environmentalism! Eco-group leaders polled by People magazine voted Ron and Alan the Number One Enemy of the Earth they'd like to see livivng next to a toxic waste dump. Everybody is talking about them. Time magazine said, .in the wise-use movement, its ideologues are Ron Arnold, a former Sierra Clubber who did a philosopical backflip, and Alan Gottlieb, a longtime fundraiser for conservative causes. The New York Times wrote, Mr. Gottlieb is the most successful fund-raiser working to tap a growing movement of loggers, ranchers, miners, oil drillers, dirt-bike riders and others who view big environmental groups as a threat to their livelihood and way of life. The Washington Post wrote, A former Sierra Club official... Arnold says he still considers himself a strong conservationist. But he accuses mainstream groups of exaggerating or even inventing environmental threats in order to advance narrow political goals that have little to do with safeguarding natural resources.
