采用回溯法，利用动态搜索树的数据结构来构造一棵解树，实现3着色问题。 本程序使用迭代回溯算法-The use of retrospective law, the use of dynamic search tree data structure to construct a solution tree, the realization of 3 coloring problem. This procedure backtrackin

此算法为三色算法，采用OMNET++实现，对学习OMNET++的人会有帮助的！-This algorithm for three-color algorithm, using OMNET++ implementation, learning OMNET++ people will help!
