这是两篇非常好的讲怎么样对SVM的参数优化，可以从中学习进而对SVM算法改进-This is two very good speakers on how to optimize the SVM parameters, you can learn and thus improve the SVM algorithm

模拟退火算法的代码以及使用模拟退火法寻优SVM中的参数c和g(The code of simulated annealing algorithm and the use of simulated annealing to optimize the parameters c and G in SVM)
