This monograph deals with random forests and aims to show that, despite the outward simplicity of the forest graph design, the problems emerging in relation to the phenomenon are challenging, and their solution often requires subtle mathematical methods. The book focuses on forests formed by simply generated trees. While the notion of the simply generated family of trees covers many known tree classes, this approach to the study of random forests gives a chance to obtain results for various forest types in a uniform way. The main objective of the book is to provide the full description of the...
