The reason I wanted to learn the Hybrid A* algorithm was that I took a class in self-driving cars, where the teacher showed a really cool video with a car that drove around in a maze until it found the goal: 0 The problem was that the teacher didn't explain the Hybrid A* algorithm...
However, the requirement for an algorithm for efficient path planning still exists. This paper presents a new hybrid algorithm based on the concept of A* algorithm and visibility graph algorithm to solve robotic path planning problems. The hybrid algorithm utilizes the advantages of both algorithms ...
Hybrid A * algorithm has been widely used in mobile robots to obtain paths that are collision-free and drivable. However, the outputs of hybrid A * algorithm always contain unnecessary steering actions and are close to the obstacles. In this paper, the artificial potential field (APF) concept...
A one-spin (n = 1) and two-spin (n = 2) system, respectively, shown in a, b, have 2k and 22k different histories. Here, k = 3 in a and k = 2 in b Full size image Hybrid algorithm for finding consistent histories We refer to our VHQCA as Variational ...
整个Open Space Planner 挺复杂的, 这篇博文先分析第一步里的 Hybrid A* 生成粗轨迹的模块. 这个模块位于planing/open_space/coarse_trajectory_generator目录下. Apollo 使用了 Hybrid A* 结合车辆动力学搜索出 Path 后进行速度规划, 复杂一点的速度规划利用 QP 求解出 piecewise quintic polynominal, 从而规划出一...
The ant colony optimization (ACO) is one efficient approach for solving the travelling salesman problem (TSP). Here, we propose a hybrid algorithm based on

To overcome the disadvantages of premature convergence and easy trapping into local optimum solutions, this paper proposes an improved particle swarm optimization algorithm (named NDWPSO algorithm) based on multiple hybrid strategies. Firstly, the elite
The goal of the thesis and hence this code is to create a real-time path planning algorithm for the nonholonomic Research Concept Vehicle (RCV). The algorithm uses a binary obstacle map as an input, generated using LIDAR mounted on top of the vehicle. The algorithm is being developed using...
