Magic and antimagic labelings are among the oldest labeling schemes in graph theory. This book takes readers on a journey through these labelings, from early beginnings with magic squares up to the latest results and beyond. Starting from the very basics, the book offers a detailed account of all magic and antimagic type labelings of undirected graphs. Long-standing problems are surveyed and presented along with recent results in classical labelings. In addition, the book covers an assortment of variations on the labeling theme, all in one self-contained monograph. Assuming only basic familiarity with graphs, this book, complete with carefully written proofs of most results, is an ideal introduction to graph labeling for students learning the subject. More than 150 open problems and conjectures make it an invaluable guide for postgraduate and early career researchers, as well as an excellent reference for established graph theorists.

This book is a generous presentation of all of the figures and events of what most consider to be the greatest era in boxing history. The first chapter compares the seventies to all of the other eras from Jack Johnson (1908-1915) up to the present day Klitcko brothers. Through an established set of criteria, the contention is proven that the seventies stands above all other eras. Chapter two covers the tumultuous 1960s and the circumstances that led to the blossoming of unprecedented competition. The remaining ten chapters cover the years 1970 through to 1979, reliving the rivalries, animosities and stories of an era that produced such household names as Ali, Frazier, Foreman, Norton and Holmes. It was a time when even those with no interest in sports knew the names of these legends.

This book constitutes the refereed post-conference proceedings of the 28th International Workshopon Combinatorial Algorithms, IWOCA 2017, held in Newcastle, NSW, Australia, in July 2017.The 30 regular papers presented in this volume together with 5 invited talks were carefully reviewed and selected from 55 submissions. They were organized in topical sessions named: approximation algorithms and hardness; computational complexity; computational geometry; graphs and combinatorics; graph colourings, labellings and power domination; heuristics; mixed integer programming; polynomial algorithms; privacy; and string algorithms.

After a hundred year mission, Roy Manning and the crew of the Glory were looking forward to returning to Earth. Unknown to them, the Medcorians, one of the two races they met in the Pollack System, destroyed their replacement, the Star Ship Inspiration, and went through a magical machine called, the teacher, and changed Earth's history so they would never visit their planet. Follow Manning, as he tries to understand his inner feelings of an adventure that the rest of his crew doesn't remember, and solve the riddles of an Earth that was destroyed by a Roman Empire that never fell. Join Doctor Arnold, as she attempts to save the only person that can help them, and Backman, along with Lamar, a Usian that followed them by going through the teacher, as they, and the last few American Indians prepares to do battle to save North America.

While investigating what appeared to be an accidental death of a stripper, Detective Jake Casey, and his partner, Macs, had their doubts. The girl's best friend, Karen, tells them that she was only in her twenties, and just started to look much older, and the coroner said she was suffering from osteoporosis. This was something Casey didn't think possible; especially after her friend tells him she was healthy and strong only a few days ago. When the coroner is murdered, and the girl's body is burnt to ashes, Casey is convinced there is some kind of cover-up, but he couldn't fathom how deep into the evils of the drug world and perverted sex he would have to go to find the man responsible. As Casey follows every lead, that seemed to pop up from nowhere, they also seem to end as his bosses stop him in his tracks. Beginning to feel like a pawn in a game, he is given another lead about a man called Four, who not only is a genus, but had an overwhelming gift to make whoever he wanted obey his every command by just a glance. the only witness he had, and watch a small town be sacrificed as he tries to solve the puzzle of Four's hideous desires, knowing that he'd stop at nothing to accomplish his demented goal of killing millions.
