This book is a continuation of the research program presented in my previous books (and those books will be frequently referred to here, by the nicknames EM and CL).

A BRIEF HISTORY OF RESEARCH ON R&T In his pioneering work on human play, Groos (1901) described many kinds of rough-and-tumble play. However, R&T was virtually an ignored topic from then until the late 1960's.

The book then goes on to cover approximation and sampling techniques and is rounded off by an in-depth case study. A well-paced and wide-ranging introduction to this subject.
