Download or read book Mazes for Programmers written by Jamis Buck and published by Pragmatic Bookshelf. This book was released on 2015-07-15 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unlock the secrets to creating random mazes! Whether you're a game developer, an algorithm connoisseur, or simply in search of a new puzzle, you're about to level up. Learn algorithms to randomly generate mazes in a variety of shapes, sizes, and dimensions. Bend them into Moebius strips, fold them into cubes, and wrap them around spheres. Stretch them into other dimensions, squeeze them into arbitrary outlines, and tile them in a dizzying variety of ways. From twelve little algorithms, you'll discover a vast reservoir of ideas and inspiration. From video games to movies, mazes are ubiquitous. Explore a dozen algorithms for generating these puzzles randomly, from Binary Tree to Eller's, each copiously illustrated and accompanied by working implementations in Ruby. You'll learn their pros and cons, and how to choose the right one for the job. You'll start by learning six maze algorithms and transition from making mazes on paper to writing programs that generate and draw them. You'll be introduced to Dijkstra's algorithm and see how it can help solve, analyze, and visualize mazes. Part 2 shows you how to constrain your mazes to different shapes and outlines, such as text, circles, hex and triangle grids, and more. You'll learn techniques for culling dead-ends, and for making your passages weave over and under each other. Part 3 looks at six more algorithms, taking it all to the next level. You'll learn how to build your mazes in multiple dimensions, and even on curved surfaces. Through it all, you'll discover yourself brimming with ideas, the best medicine for programmer's block, burn-out, and the grayest of days. By the time you're done, you'll be energized and full of maze-related possibilities! What You Need: The example code requires version 2 of the Ruby programming language. Some examples depend on the ChunkyPNG library to generate PNG images, and one chapter uses POV-Ray version 3.7 to render 3D graphics.

Tessa doesn’t want to end her career as a loser. She really enjoys playing, and if she’s being honest, she likes it even more than running cross-country. So what if she decided to play football instead? What would happen between her and Caleb? Or between her two best friends, who are counting on her to try out for cross-country with them?

Download or read book Albion s Seed written by David Hackett Fischer and published by Oxford University Press. This book was released on 1991-03-14 with total page 981 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fascinating book is the first volume in a projected cultural history of the United States, from the earliest English settlements to our own time. It is a history of American folkways as they have changed through time, and it argues a thesis about the importance for the United States of having been British in its cultural origins. While most people in the United States today have no British ancestors, they have assimilated regional cultures which were created by British colonists, even while preserving ethnic identities at the same time. In this sense, nearly all Americans are "Albion's Seed," no matter what their ethnicity may be. The concluding section of this remarkable book explores the ways that regional cultures have continued to dominate national politics from 1789 to 1988, and still help to shape attitudes toward education, government, gender, and violence, on which differences between American regions are greater than between European nations.

Book excerpt: “Redefines ‘unputdownable.’” —Amie Kaufman, New York Times bestselling author of Iluminae “I was thrilled. I was shocked.” —NPR “Stunning twists and turns.” —BCCB (starred review) In this gripping debut novel, seventeen-year-old Cat must use her gene-hacking skills to decode her late father’s message concealing a vaccine to a horrifying plague. Catarina Agatta is a hacker. She can cripple mainframes and crash through firewalls, but that’s not what makes her special. In Cat’s world, people are implanted with technology to recode their DNA, allowing them to change their bodies in any way they want. And Cat happens to be a gene-hacking genius. That’s no surprise, since Cat’s father is Dr. Lachlan Agatta, a legendary geneticist who may be the last hope for defeating a plague that has brought humanity to the brink of extinction. But during the outbreak, Lachlan was kidnapped by a shadowy organization called Cartaxus, leaving Cat to survive the last two years on her own. When a Cartaxus soldier, Cole, arrives with news that her father has been killed, Cat’s instincts tell her it’s just another Cartaxus lie. But Cole also brings a message: before Lachlan died, he managed to create a vaccine, and Cole needs Cat’s help to release it and save the human race. Now Cat must decide who she can trust: The soldier with secrets of his own? The father who made her promise to hide from Cartaxus at all costs? In a world where nature itself can be rewritten, how much can she even trust herself?

Book excerpt: A 2015 Whitney Award Nominee! A powerful story of loss, second chances, and first love, reminiscent of Sarah Dessen and John Green. When Oakley Nelson loses her older brother, Lucas, to cancer, she thinks she’ll never recover. Between her parents’ arguing and the battle she’s fighting with depression, she feels nothing inside but a hollow emptiness. When Mom suggests they spend a few months in California with Aunt Jo, Oakley isn’t sure a change of scenery will alter anything, but she’s willing to give it a try. In California, Oakley discovers a sort of safety and freedom in Aunt Jo’s beach house. Once they’re settled, Mom hands her a notebook full of letters addressed to her—from Lucas. As Oakley reads one each day, she realizes how much he loved her, and each letter challenges her to be better and to continue to enjoy her life. He wants her to move on. If only it were that easy. But then a surfer named Carson comes into her life, and Oakley is blindsided. He makes her feel again. As she lets him in, she is surprised by how much she cares for him, and that’s when things get complicated. How can she fall in love and be happy when Lucas never got the chance to do those very same things? With her brother’s dying words as guidance, Oakley knows she must learn to listen and trust again. But will she have to leave the past behind to find happiness in the future?

Download or read book Reinforcement Learning second edition written by Richard S. Sutton and published by MIT Press. This book was released on 2018-11-13 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significantly expanded and updated new edition of a widely used text on reinforcement learning, one of the most active research areas in artificial intelligence. Reinforcement learning, one of the most active research areas in artificial intelligence, is a computational approach to learning whereby an agent tries to maximize the total amount of reward it receives while interacting with a complex, uncertain environment. In Reinforcement Learning, Richard Sutton and Andrew Barto provide a clear and simple account of the field's key ideas and algorithms. This second edition has been significantly expanded and updated, presenting new topics and updating coverage of other topics. Like the first edition, this second edition focuses on core online learning algorithms, with the more mathematical material set off in shaded boxes. Part I covers as much of reinforcement learning as possible without going beyond the tabular case for which exact solutions can be found. Many algorithms presented in this part are new to the second edition, including UCB, Expected Sarsa, and Double Learning. Part II extends these ideas to function approximation, with new sections on such topics as artificial neural networks and the Fourier basis, and offers expanded treatment of off-policy learning and policy-gradient methods. Part III has new chapters on reinforcement learning's relationships to psychology and neuroscience, as well as an updated case-studies chapter including AlphaGo and AlphaGo Zero, Atari game playing, and IBM Watson's wagering strategy. The final chapter discusses the future societal impacts of reinforcement learning.
