I think another project can be invoke-------------a project about calculating the most valuable route.It can help designer to create map and player to enjoy the game.
I am a newbie and I got confused about make the structure of data.For example,I consider the city(may be town/country in game) as a point and it has an array which contains next step information and its attributes.The array element stores next step city id and the step length and the array length indicates the branch numbers.

But if data is designed like this ,it means a fairly amount data is duplicate.When I find this phenomenon,I think I make a mistake: judge things from their relationships instead of themselves.
But then how to make the data structure？

我觉得可以做一个计算slg游戏贸易路线的程序。追求单位路线长度利润最大，或者是资金周转比较快。
采用什么数据结构比较好，谢谢。
