Global path planning for inland vessels based on fast marching algorithm
Ocean EngineeringShip path planning is essential for enhancing navigation safety, shipping efficiency, cost savings and autonomy. This paper presents a path planning algorithm specifically designed for inland vessels, exemplified on the Western Scheldt waterway area from Hansweert to Bath in the Netherlands (known as the area of Schaar van Valkenisse).

Wildfire Spreading Simulator Using Fast Marching Algorithm [PDF]
SNE Simulation Notes Europe, 2021 Programs that can predict wildfire behavior are a very useful tool in terms of extinguishing these fires more effectively. State of the art wildfire simulators present some drawbacks such as not being sufficiently user-friendly, being expensive, requiring great computational power or having poor graphical representation. This paper presents a prototype

A two-layered fast marching path planning algorithm for an unmanned surface vehicle operating in a dynamic environment [PDF]
OCEANS 2015 - Genova, 2015 This paper describes a modified fast marching (FM) path planning algorithm for unmanned surface vehicles (USVs). The modified FM algorithm generates a two-layered synthetic vector field to represent a dynamic environment. The synthetic vector field integrates the obstacle information and the environment information, where current and wind velocities ...

An Efficient Path Planning Algorithm for Biped Robot using Fast Marching Method
Procedia Computer Science, 2018 Abstract An efficient path planning algorithm is required for the robot to move in a complex known and unknown environments. In the present research, the authors made an attempt to develop a path planning algorithm, that is, fast marching method (FMM) for the biped robot to move in a static environment.

A Fast-marching Algorithm for Nonmonotonically Evolving Fronts [PDF]
SIAM Journal on Scientific Computing, 2016 The non-monotonic propagation of fronts is considered. When the speed function $F:\mathbb{R}^{n} \times [0,T]\rightarrow \mathbb{R}$ is prescribed, the non-linear advection equation $ϕ_{t}+F|\nabla ϕ|=0$ is a Hamilton-Jacobi equation known as the level-set equation.
