[拜倒求助] 有关label 自动定位的快速算法

<P>各位前辈：</P>
<P>      哥们可以说是个新手，不过我做的不是应用平台开发webGIS，而是，设计和应用一个算法，解决在制图（web service or moblie service）中label 的自动定位问题。所以有个问题请教大家，如果有和我一样做算法的，可以给我点指教，目前为了满足interaction service or personal navigation, 所以webMAP中的label 都是在每次服务请求到来的时候重定位， 所以，我现在迫切需要一个快速的算法对label 的重定位问题作出解决，</P>
<P>       拜倒求助，</P>
