论文《An Admissible Heuristic to Improve Convergence in Kinodynamic Planners Using Motion Primitives》 最近遇到的问题是,lattice plannner很难到点,虽然加上了dubins shot,但是还是有些情况下一直在终点附近扩展,却到达不了。 归根到底,因为用Dijkstra作为启发值,本身就不合适,那我模仿混合A*的做法,取max(Dijkstra,...

Abstract Admissible heuristics are an important class of heuristics worth discovering: they guarantee shortest path solutions in search algorithms such asA*and they guarantee less expensively produced, but boundedly longer solutions in search algorithms such as dynamic weighting. Unfortunately, effective (acc...

In computer science, a heuristic function is said to be admissible if it is no more than the lowest-cost path to the goal. In other words, a heuristic is admissible if it never overestimates the cost of reaching the goal. An admissible heuristic is also known as an optimistic heuristic....
AND/OR graphs play a major role in heuristic problem solving. Martelli and Montanari (1973) have developed an elegant algorithm, called HS, for heuristic search in AND/OR graphs, which they have used for converting decision tables to programs. It has so long been thought that HS yields minim...
time, we introduce an additive heuristic that is also admissi- ble. The idea is simple: Given the heuristic h m and a parti- tioning of the set of actions into disjoint sets A 1 , . . . , A n , we define additive h m as the sum i h m Ai , where h m Ai is defi...

We analyze the asymptotic time complexity of admissible heuristic search algorithms such as A*, IDA*, and depth-first branch-and-bound. Previous analyses relied on an abstract analytical model, and characterize the heuristic function in terms of its accuracy, but do not apply to real problems. ...
The results show that the pro-posed heuristic is efficient as A* is able to reach optimal solutions for instances that are not always solved to op-timality with the local search procedure; even running for a larger time. 展开 会议名称: COPLAS 2008 Workshop on Constraint Satisfaction ...
