Sommario/riassunto

An overview of developments in the past 15 years of adjunction theory, the study of the interplay between the intrinsic geometry of a projective variety and the geometry connected with some embedding of the variety into a projective space. Topics include consequences of positivity, the Hilbert schem

Sommario/riassunto

Although rarely seen in the wild, the otter is admired for its playful character and graceful aquatic agility, which were established in the popular imagination through books like Tarka the Otter and Ring of Bright Water. This, however, is just a very small part of their story-throughout history the otter has also been widely hunted for its fur and flesh.  In Otter, human geographer Daniel Allen reveals how the animal's identity has been shaped by this variety of human interactions.  As Allen explains, otters, while feared by some communities, were hun

Sommario/riassunto

This book is devoted to the state-of-the-art in all aspects of fireworks algorithm (FWA), with particular emphasis on the efficient improved versions of FWA. It describes the most substantial theoretical analysis including basic principle and implementation of FWA and modelling and theoretical analysis of FWA. It covers exhaustively the key recent significant research into the improvements of FWA so far. In addition, the book describes a few advanced topics in the research of FWA, including multi-objective optimization (MOO), discrete FWA (DFWA) for combinatorial optimization, and GPU-based FWA for parallel implementation. In sequels, several successful applications of FWA on non-negative matrix factorization (NMF), text clustering, pattern recognition, and seismic inversion problem, and swarm robotics, are illustrated in details, which might shed new light on more real-world applications in future. Addressing a multidisciplinary topic, it will appeal to researchers and professionals in the areas of metaheuristics, swarm intelligence, evolutionary computation, complex optimization solving, etc.
