Hamilton problem is one of fundamental problems in graph theory , the following aspects are mainly focused on : cycle problem and path problem . in detail , they are mainly problems of hamilton cycle , cycle extensibility , longest cycle and hamilton path , hamilton - connectivity , panconnectivity , path extensibility , longest path etc . as to hamilton cycle problem , we have got many results Hamilton问题是图论研究的基本问题之一,主要集中在以下两个方面:圈问题和路问题,具体地讲主要有: hamilton圈问题,圈可扩性问题,最长圈问题等以及hamilton路问题, hamiltonj ji问题,泛溯问题,路可扩性问题,最长路问题等
The find - path problem is then transformed into that of finding a collision - free path for a point robot among the cspace obstacles . however , the research experiences have shown that the cspace transformation is very hard when the following situations occur : 1 both the robot and obstacles are not polygons , and 2 the robot is allowed to rotate . this situation gets even worse when the robot and obstacles are three dimensional objects with various shapes 其根本问题有二:第一,这一方法只适用于机器人及障碍物形状均为2d空间的多边形,无法推广到3d空间的多面体和其它形状的3 d空间物体,从而表现为对机器人及障碍物形状敏感第二,这一方法只适用于机器人平动,而实际机器人都必然要包括转动的要求。
