| Summary |
Algorithms have always played an important role both in the science and practice of computing. Beyond traditional computing, ability to utilize these algorithms to solve real-world problems is an important skill and is the focus of this book. In order to optimally use these algorithms, a deeper understanding of their logic and mathematics is ... |
