AMPL is a language for large-scale optimization and mathematical programming problems in production, distribution, blending, scheduling, and many other... applications. Combining familiar algebraic notation and a powerful interactive command environment, AMPL makes it easy to create models, use a wide variety of solvers, and examine solutions. Though flexible and convenient for rapid prototyping and development of models, AMPL also offers the speed and generality needed for repeated large-scale production runs. This book, written by the creators of AMPL, is a complete guide for modelers at all levels of experience. It begins with a tutorial on widely used linear programming models, and presents all of AMPL's features for linear programming with extensive examples. Additional chapters cover network, nonlinear, piecewise-linear, and integer programming; database and spreadsheet interactions; and command scripts. Most chapters include exercises. Download free versions of AMPL and several solvers from www.ampl.com for experimentation, evaluation, and education. The Web site also lists vendors of the commercial version of AMPL and numerous solvers.

This book, the first full-length study of its kind, dares to probe the biggest taboo in contemporary Arab culture with scholarly intent and integrity -... female homosexuality. Habib argues that female homosexuality has a long history in Arabic literature and scholarship, beginning in the ninth century, and she traces the destruction of Medieval discourses on female homosexuality and the replacement of these with a new religious orthodoxy that is no longer permissive of a variety of sexual behaviours. Habib also engages with recent "gay" historiography in the West and challenges institutionalized constructionist notions of sexuality.

On a chilly February day, two old friends meet in the throng outside a London crematorium to pay their last respects to Molly Lane. Both Clive Linley... and Vernon Halliday had been Molly's lovers in the days before they reached their current eminence: Clive is Britain's most successful modern composer, and Vernon is editor of the newspaper The Judge. Gorgeous, feisty Molly had other lovers, too, notably Julian Garmony, Foreign Secretary, a notorious right-winger tipped to be the next prime minister.In the days that follow Molly's funeral, Clive and Vernon will make a pact with consequences that neither could have foreseen. Each will make a disastrous moral decision, their friendship will be tested to its limits, and Julian Garmony will be fighting for his political life. A sharp contemporary morality tale, cleverly disguised as a comic novel, Amsterdam is "as sheerly enjoyable a book as one is likely to pick up this year" (The Washington Post Book World).

No one has written more feelingly and more beautifully than Nescio about the madness and sadness, courage and vulnerability of youth: its big plans and... vague longings, not to mention the binges, crashes, and marathon walks and talks. No one, for that matter, has written with such pristine clarity about the radiating canals of Amsterdam and the cloud-swept landscape of the Netherlands. Who was Nescio? Nescio—Latin for “I don’t know”—was the pen name of J.H.F. Grönloh, the highly successful director of the Holland–Bombay Trading Company and a father of four—someone who knew more than enough about respectable maturity. Only in his spare time and under the cover of a pseudonym, as if commemorating a lost self, did he let himself go, producing over the course of his lifetime a handful of utterly original stories that contain some of the most luminous pages in modern literature. This is the first English translation of Nescio’s stories.

A tour de force, Amulet is a highly charged first-person, semi-hallucinatory novel that embodies in one woman's voice the melancholy and violent recent... history of Latin America.Amulet is a monologue, like Bolaño's acclaimed debut in English, By Night in Chile. The speaker is Auxilio Lacouture, a Uruguayan woman who moved to Mexico in the 1960s, becoming the "Mother of Mexican Poetry," hanging out with the young poets in the cafés and bars of the University. She's tall, thin, and blonde, and her favorite young poet in the 1970s is none other than Arturo Belano (Bolaño's fictional stand-in throughout his books). As well as her young poets, Auxilio recalls three remarkable women: the melancholic young philosopher Elena, the exiled Catalan painter Remedios Varo, and Lilian Serpas, a poet who once slept with Che Guevara. And in the course of her imaginary visit to the house of Remedios Varo, Auxilio sees an uncanny landscape, a kind of chasm. This chasm reappears in a vision at the end of the book: an army of children is marching toward it, singing as they go. The children are the idealistic young Latin Americans who came to maturity in the '70s, and the last words of the novel are: "And that song is our amulet."

La voz arrebatada de Auxilio Lacouture narra, e indaga, un crimen atroz y lejano, que solo se desvelará en las últimas páginas de una novela en la... que, por otra parte, no escasean los crímenes cotidianos y los crímenes de la formación del gusto artístico. Ella es uruguaya de mediana edad, alta y flaca, y se oculta en los lavabos de mujeres de la Facultad de Filosofía y Letras durante la toma de la universidad por la policía, en México, en septiembre de 1968. Allí está durante varios días, y el lavabo se convertirá en un túnel del tiempo desde el cual avizorar los años ya vividos en México y los años por vivir. En su discurso rememora a la poetisa Lilian Serpas, que hizo el amor con el Che, y a su infortunado hijo, a los poetas españoles León Felipe y Pedro Garfias, a la pintora catalana Remedios Varo y su legión de gatos, al rey de los homosexuales de la colonia Guerrero y su reino de terror gestual. Pero sobre todo se narra un viaje por un mundo, el Polo Norte de la memoria que se extiende por doquier, y la imagen última de un asesinato olvidado.

Auxilio, uruguaya de mediana edad, se oculta en los lavabos de mujeres... durante la toma de la universidad por la policia, en Mexico, en septiembre de 1968. Recluida alli por varios dias, podra avizorar los anos ya vividos en Mexico y los anos por vivir. Rememora entonces a la poetisa Lilian Serpas, que hizo el amor con el Che, y a su infortunado hijo, a los poetas espanoles Leon Felipe y Pedro Garfias a quienes Auxilio sirvio como domestica voluntaria, y tambien aparece Arturo Belano, personaje central en Los detectives salvajes, de la que esta novela es una digresion fractal. Pero sobre todo se narra un viaje por un mundo, el Polo Norte de la memoria que se extiende por doquier. «Consigue dar vida a un personaje que sin duda quedara grabado en la memoria del lector» (Ignacio Martinez de Pison, ABC); «En lugar de ser un libro menor, es una obra mas arriesgada y, por tanto, mas minoritaria que Los detectives salvajes» (Mihaly Des, Lateral).
