#### Media Theory

Springer Berlin Heidelberg 2007; US$ 119.00The focus of this book is a mathematical structure modeling a physical or biological system that can be in any of a number of ?states. ? Each state is characterized by a set of binary features, and di?ers from some other nei- bor state or states by just one of those features. In some situations, what distinguishes a state S from a neighbor state T... more...
