最短路径

Firstly, a spherical mesh with regular subdivision connectivity is constructed to partition the spherical domain into some small regions. Then the region, which contains the query point p, is found according to the position of p and selected as the search area for locating p. During the point location, the barycentric coordinates are used to extract local heuristic information about the location of p so as to find the shortest path from the start triangle to the target one containing p.

通过构造规则子分网格将原始球面网格区域划分成若干具有子分层次关系的查询小块；在进行查询前，根据查询点p的位置找到它所在的小块作为搜索区域，从而极大地缩小了查询范围；在查询过程中，根据重心坐标所包含的启发信息，选择一条从初始搜索三角形到目标三角形的最短查询路径。

The shortest path between two truths in the real domain passes through the complex domain.

迷路后入路采用不同联合方式，对脑干腹外侧除颅颈交界区外的巨大肿瘤可以良好显露，术野开阔，路径短，脑牵拉轻，可多视角操作，影响术后效果的最主要因素可能为血管因素和肿瘤对脑干的压迫程度。

based on wilensky's ant colony foraging model and considers additional nature rules including multispecies, competition and evolution mechanism,promoted antcolonysim model.it carried out simulations based on antcolonysim under different conditions as well as emergent properties including foraging predominance and analyzed competition predominance.

摘 要：在wilensky蚁群觅食模型基础之上，增加了多样性、竞争机制和进化机制，提出了人工蚁群觅食行为仿真模型。通过对该模型的仿真，分析了不同条件下的系统整体涌现属性，包括最短觅食路径、蚁群觅食优势和竞争优势。
