计算PI的算法，并行性很好，大家可以试试，用eclipse编译通过-PI calculation algorithms, parallel is very good, we can try compile with eclipse

阻尼算法实现优化，主要是针对线性方程组求解超定方程的一种算法。大家可以试试。-Damping algorithm to realize optimization

dijkstra algorithm 用来描述最短路径,这里是并行化的实线.希望大家有时间试试,用的是openmp-dijkstra algorithm is used to describe the shortest path, here it is the parallelism of the solid line. I hope you have time to try, using a openmp
