Lazy theta

WebIn recent years, the problem of route planning in complex battlefield environments has attracted significant attention. With the increasingly worrying international situation, safety and flyability in a continuously changing threat environment are critical factors in route planning research. Thus, this paper proposes an improved Lazy Theta* algorithm that … Web28 apr. 2024 · Lazy_Theta_star是在 Theta_star上的进一步改进，Theta_star是当节点加入open表时和当前点的父节点进行比较g值是否更小，对一些不必要的节点计算浪费了时间，而Lazy_Theta_star则是在弹出open表后进行比较，减少了不必要点的计算。

Web13 jan. 2024 · The lazy theta∗ algorithm is judged by the line-of-sight algorithm, and the intermediate node can be omitted, hence the number of nodes is small. By reducing the number of nodes, the algorithm also reduces the path searching time and path cost. The improved lazy theta∗ algorithm has short search time, short length and few nodes.
