摘要:

基于深度学习的方法在规划方面越来越重要。在本文中,我们提出了一种混合规划器,结合了图机器学习模型和基于分支和边界树搜索的路径规划任务的最佳求解器。更具体地,使用图神经网络来辅助分支定界算法处理与期望解路径相关联的约束。有多个下游实际应用,例如自主无人地面车辆(AUGV),通常部署在救灾或搜索和救援行动中。在越野环境中,AUGV必须在各种操作约束下动态优化源-目的地路径,其中一些操作约束难以提前预测并且需要在线解决。我们进行实验,现实的情况下,并表明,图神经网络的支持,使大量的加速和更平滑的扩展到更难的路径规划问题。此外,由图神经网络提供的信息使该方法能够优于特定问题的手工算法,突出了潜在的图神经网络持有的路径规划任务。

英文摘要:

Deep learning-based methods are growing prominence for planning purposes. In this paper, we present a hybrid planner that combines a graph machine learning model and an optimal solver based on branch and bound tree search for path-planning tasks. More specifically, a graph neural network is used to assist the branch and bound algorithm in handling constraints associated with a desired solution path. There are multiple downstream practical applications, such as Autonomous Unmanned Ground Vehicles (AUGV), typically deployed in disaster relief or search and rescue operations. In off-road environments, AUGVs must dynamically optimize a source-destination path under various operational constraints, out of which several are difficult to predict in advance and need to be addressed online. We conduct experiments on realistic scenarios and show that graph neural network support enables substantial speedup and smoother scaling to harder path-planning problems. Additionally, information provided by the graph neural network enables the approach to outperform problem-specific handcrafted heuristics, highlighting the potential graph neural networks hold for path-planning tasks.
