摘要
通过对地图数据的预处理和启发函数的设计,对A*算法进行了改进。利用VC++编程实现改进算法,并在实际城市地图上对改进算法进行了验证,结果表明改进算法提高了搜索最优路径的成功率,同时解决了原算法易出现搜索死循环的问题,可适应不规则的城市路网。
A＊ algorithm was improved by pre-treating map data and selecting appropriate developmental function. An experiment was carried out by coding with VC＋＋. The result showed that the improved algorithm increased success rate of optimal path searching, and solved repetition problem of A＇algorithm. This algorithm could adapt well to irregular city path network.
