1·The algorithm is very simple and suitable for finding all undirected Hamiltonian circuits in general undigraph.
算法简便，适合于求解一般无向图中全部哈密顿回路。
2·Based on analyzing existed structures of undigraph and characteristics of 2d drawing, Classified Adjacency List which is an improving structure of undigraph is presented.
在充分分析现有无向图存储结构优缺点的基础上，结合二维工程图形的特点，提出了一种改进的无向图存储结构——分类邻接表存储结构。
3·To solve the model, the shortest path and its length of every two nodes in the incomplete undigraph are calculated with FLOYD algorithm, and a predatory search algorithm is designed for the solution.
为了求解上述模型，首先利用FLOYD算法求得不完全无向图中各节点间的最短路径和最短路径长度，然后设计了捕食搜索算法对模型进行求解。
