These are hard instances for graph isomorphism problem. Due to https://www.lics.rwth-aachen.de/go/id/rtok/. http://www.tcs.hut.fi/Software/bliss/benchmarks/index.shtml http://pallini.di.uniroma1.it/Graphs.html In edgelist format. To be continued.本数据集包含图同构问题（graph isomorphism problem）的困难测试实例，相关数据来源于以下站点：https://www.lics.rwth-aachen.de/go/id/rtok/、http://www.tcs.hut.fi/Software/bliss/benchmarks/index.shtml 以及 http://pallini.di.uniroma1.it/Graphs.html。数据集采用边列表（edgelist）格式存储。未完待续。
