Collision avoidance tree networks [PDF]
Computer Networks and ISDN Systems, 1994 Abstract The Collision Avoidance Tree is a local area network based on a hardware device called the collision avoidance switch. The collision avoidance switch arbitrates random access to a shared communication channel and avoids the penalty of collisions among packets.

Multi-ship Coordinated Collision Avoidance Decision Based on Improved Twin Delayed Deep Deterministic Policy Gradient [PDF]
Jisuanji kexue, 2023 At present,most models of collision avoidance algorithms take ships as single agent to make collision avoidance decisions,without considering the coordinated avoidance between ships.In the scenario of multi-ship meeting,it will lead to poor avoidance ...

Optimization-Based Collision Avoidance [PDF]
IEEE Transactions on Control Systems Technology, 2021 This paper presents a novel method for reformulating non-differentiable collision avoidance constraints into smooth nonlinear constraints using strong duality of convex optimization. We focus on a controlled object whose goal is to avoid obstacles while moving in an n-dimensional space.

Differentiable Collision Avoidance Using Collision Primitives
2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2022 A central aspect of robotic motion planning is collision avoidance, where a multitude of different approaches are currently in use. Optimization-based motion planning is one method, that often heavily relies on distance computations between robots and obstacles.
