说明：  C语言趣味程序百例精解，是PDF格式。里面有很多趣味的例子，大大小小的算法都有，可谓是算法的经典。这个是学习算法的好资料，在学习中找到趣味，完全不同于其他资料的算法枯燥无味(C language program 100 cases of sperm interesting solution is in PDF format. There are many interesting examples of both large and small algorithm, the algorithm can be described as classic. This is a learning algorithm is good information, in learning to find interesting information is completely different from other algorithms dull)

if a radio configuration is given, what are its anticipated capabilities (e.g., in terms of achievable data rate), taking into account recent information sensed, as well as the past experience and knowledge?”.Here learning schemes are considered for basic and extended based on neural networks and ANFIS are designed to enhance the learning capabilities of a cognitive terminal, in terms of assisting it to predict the data rate that a specific radio configuration could achieve if it was selected for operation.
