本书对SQL技术的使用和发展进行了全面的讨论。全书共分六大部分，其中第一部分到第五部分分别介绍了SQL的历史和SQL标准的变化，如何使用SQL获取、更新数据，如何构造数据库结构以及如何实现数据的安全方案等，并描述了如何使用ANSI标准中的嵌入式SQL。(This book SQL technology use and development of a comprehensive discussion. The book is divided into six large part to the fifth part of the first part of which introduced the history and the SQL standard SQL changes, how to use SQL to obtain, update data, how to construct the database structure and how to implement data security programs, and describes the How to use the ANSI standard for embedded SQL.)

Solving NP-hard discrete optimization problems to optimality is often an immense job requiring very ecient algorithms, and the B&B paradigm is one of the main tools in construction of these. A B&B algorithm searches the complete space of solutions for a given problem for the best solution. However, explicit enumeration is normally impossible due to the exponentially increasing number of potential solutions. The use of bounds for the function to be optimized combined with the value of the current best solution enables the algorithm to search parts of the solution space only implicitly.

说明：  A commented bash script to generate our final 2nd place solution can be found in make_kaggle_solution.sh. Running all the commands sequentially will probably take 7 - 10 days on recent consumer grade hardware. If you have multiple GPUs you can speed things up by doing training and feature extraction for the two networks in parallel. However, due to the computationally heavy data augmentation it may be far less than twice as fast especially when working with 512x512 pixel input images. You can also obtain a quadratic weighted kappa score of 0.839 on the private leaderboard by just training the 4x4 kernel networks and by performing only 20 feature extraction iterations with the weights that gave you the best MSE validation scores during training. The entire ensemble only achieves a slightly higher score of 0.845.
