摘要:

我们提出了一个解决方案,马尔可夫决策过程的时变变量,可用于解决决策理论规划问题的自治系统在非结构化的户外环境中运行。我们探索了规划随机性的时变性并研究了状态可达性,在此基础上开发了一种有效的迭代法,该方法在解的最优性和时间复杂度之间提供了良好的权衡。通过分析状态在未来到达时间的均值和方差,构造了系统的可达性空间。我们验证了我们的算法,通过大量的模拟使用海洋数据,结果表明,我们的方法在解决方案的质量和计算时间方面取得了很大的性能。

英文摘要:

We propose a solution to a time-varying variant of Markov Decision Processes which can be used to address decision-theoretic planning problems for autonomous systems operating in unstructured outdoor environments. We explore the time variability property of the planning stochasticity and investigate the state reachability, based on which we then develop an efficient iterative method that offers a good trade-off between solution optimality and time complexity. The reachability space is constructed by analyzing the means and variances of states' reaching time in the future. We validate our algorithm through extensive simulations using ocean data, and the results show that our method achieves a great performance in terms of both solution quality and computing time.
