Direction-dependent optimal path planning for autonomous vehicles

A Shum, K Morris, A Khajepour - Robotics and Autonomous Systems, 2015 - Elsevier
The optimal path planning problem is considered for rovers. Tip-over risk is accurately
modelled using direction dependence. In the previous direction-independent model, the …

Robust shortest path planning and semicontractive dynamic programming

DP Bertsekas - Naval Research Logistics (NRL), 2019 - Wiley Online Library
In this article, we consider shortest path problems in a directed graph where the transitions
between nodes are subject to uncertainty. We use a minimax formulation, where the …

Asymptotically optimal feedback planning using a numerical Hamilton-Jacobi-Bellman solver and an adaptive mesh refinement

DS Yershov, E Frazzoli - The International Journal of …, 2016 - journals.sagepub.com
We present the first asymptotically optimal feedback planning algorithm for nonholonomic
systems and additive cost functionals. Our algorithm is based on three well-established …

Lane-level route planning for autonomous vehicles

M Jones, M Haas-Heger… - … International Journal of …, 2024 - journals.sagepub.com
We present an algorithm that, given a representation of a road network in lane-level detail,
computes a route that minimizes the expected cost to reach a given destination. In doing so …

Massively parallel computation of globally optimal shortest paths with curvature penalization

JM Mirebeau, L Gayraud, R Barrère… - Concurrency and …, 2023 - Wiley Online Library
We address the computation of paths globally minimizing an energy involving their
curvature, with given endpoints and tangents at these endpoints, according to models …

Time-dependent surveillance-evasion games

E Cartee, L Lai, Q Song… - 2019 IEEE 58th …, 2019 - ieeexplore.ieee.org
Surveillance-Evasion (SE) games form an important class of adversarial trajectory-planning
problems. We consider time-dependent SE games, in which an Evader is trying to reach its …

Evasive path planning under surveillance uncertainty

MA Gilles, A Vladimirsky - Dynamic Games and Applications, 2020 - Springer
The classical setting of optimal control theory assumes full knowledge of the process
dynamics and the costs associated with every control strategy. The problem becomes much …

Optimal control with budget constraints and resets

R Takei, W Chen, Z Clawson, S Kirov… - SIAM Journal on Control …, 2015 - SIAM
We consider both discrete and continuous control problems constrained by a fixed budget of
some resource, which may be renewed upon entering a preferred subset of the state space …
