An algorithm is a solution to a class of problems generally contained in programming unit called a module and accessed by one or more objected oriented programs. A class on algorithms is a class on problem solving with the expectation of marketable results. This requires a textbook that actually provides problem solving tools. Solving the problems is hard enough. The tools should be the easy part. Practical Algorithms provides a complete toolbox from meeting the client to rolling out a scalable solution fitting the client’s needs.

算法是一类问题的解决方案，通常包含在称为模块的编程单元中，由一个或多个面向对象的程序访问。关于算法的课程是一门关于问题解决的课程，期望得到适销对路的结果。这需要一本真正提供解决问题工具的教科书。解决这些问题已经够难了。工具应该是容易的部分。实用算法提供了一个完整的工具箱，从满足客户需求到推出适合客户需求的可扩展解决方案。
