This electronic book is devoted to deeper exploration of the fundamental concepts and algorithms that will undoubtedly fall into the category of ‘eternal’. Carefully reading this ebook, you get knowledge that will never become obsolete and that you’ll always enjoy. 
The brevity, accuracy, adjustedness, relevance, examples and teaching assignments – are just a small list of obvious advantages of this electronic book. Illustration of algorithms in one of the best programming languages C, once again underlines their popularity and ‘eternity’. 
In the ebook details the wide range of basic algorithms on graphs, including: org-graph search, neo-graph and networks, building a minimum spanning trees and shortest routes, calculate flow in networks with different characteristics. Much attention in the electronic book is given to the performance of algorithms, as well as their mathematical conclusion. 
The electronic book can be used as a course of lectures (both students and teachers), a manual or just ‘novel’ while acquiring not comparable pleasure.

The proposed ebook describes a simple and elegant solutions of typical tasks encountered in the object-oriented design. Patterns emerged because many developers looking for ways to improve the flexibility and degree of reuse programs. Found solutions embodied in a concise and easily applicable in practice form. The authors of the electronic book outlines principles of pattern design and lead their catalog. 
Thus, ebook at the same time solves two objectives. First, the electronic book demonstrates the role of patterns in creating the architecture of complex systems. 
Secondly, using the directory patterns, designer can easily develop their own applications. 
eBook is intended both for professional developers and beginner programmers, learning object-oriented design.
