How Computers Learn to Play Games of Strategy  This is book is for anyone who has ever tried to match wits with a computer in chess, bridge, or any other game requiring long-range strategy and studied decisions. If you're not a pro, chances are you've been defeated by a machine - and impressed at its uncanny ability to outmaneuver humans. In Computer Gamesmanship, David Levy, an International Chess Master and producer of intelligent computer games, unravels the mysteries of how computers successfully mimic strategic thinking and play complex games. In jargon-free language, Levy describes the important principles and techniques applicable to any game of strategy-such as decision trees, alpha-beta algorithms, minimax searches, and evaluation functions-and explains how even highly advanced strategies can be reduced to relatively simple procedures that a home computer can perform. He then illustrates and elaborates upon them in extensive discussions of the most popular and successful programs for chess, bridge, poker, Go, Othello, and many others. Computer Gamesmanship is a unique introduction and insider's guide to the most challenging games you can play, or create, on your computer.  "This is a simply written and serious little book about how computers go about playing games.... (Computer Gamesmanship] leaves the reader with a sense of admiration for the stratagems of computer programmers."

• What time is it at the North Pole? • What's the chemical formula for a human being? • Why do boomerangs come back? • Why do flying fish fly? • Do the living really outnumber the dead? • Why does lightning fork? • Why does the end of a whip crack? Everyone has at one time or another thought up odd questions like these, questions that are strange, intriguing, maybe even impossible to answer. Making your morning omelet, perhaps you've wondered why most eggs are egg shaped. Or maybe, the last time you walked on the beach, you felt compelled to ask why the sea is salty. Watching Polly sit on her perch, have you ever marveled at how she stays there -- even when she's asleep? Well, the readers of New Scientist's wildly popular, long-running column "The Last Word" thought of these questions, too, and weren't afraid to ask them. Why Don't Penguins' Feet Freeze? is a brilliant collection of questions and answers for everyone who enjoyed the international, runaway bestseller Does Anything Eat Wasps? Guaranteed to amaze, inform, and delight with topics such as the human body, plants and animals, weird weather, and our wacky world, it'll stump you, enlighten you, entertain and amuse you.
