Massively parallelizing the RRT and the RRT* [PDF]
2011 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2011 In recent years, the growth of the computational power available in the Central Processing Units (CPUs) of consumer computers has tapered significantly. At the same time, growth in the computational power available in the Graphics Processing Units (GPUs)

External quality assessment of COVID-19 real time reverse transcription PCR laboratories in India.
PLoS ONE, 2022 Sudden emergence and rapid spread of COVID-19 created an inevitable need for expansion of the COVID-19 laboratory testing network across the world. The strategy to test-track-treat was advocated for quick detection and containment of the disease.

RRT*-SMART: A Rapid Convergence Implementation of RRT* [PDF]
International Journal of Advanced Robotic Systems, 2013 Many sampling based algorithms have been introduced recently. Among them Rapidly Exploring Random Tree (RRT) is one of the quickest and the most efficient obstacle free path finding algorithm. Although it ensures probabilistic completeness, it cannot guarantee finding the most optimal path.

Fast-RRT: A RRT-Based Optimal Path Finding Method [PDF]
Applied Sciences, 2021 As a sampling-based pathfinding algorithm, Rapidly Exploring Random Trees (RRT) has been widely used in motion planning problems due to the ability to find a feasible path quickly. However, the RRT algorithm still has several shortcomings, such as the large variance in the search time, poor performance in narrow channel scenarios, and being far from ...

Blind RRT: A probabilistically complete distributed RRT [PDF]
2013 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2013 Rapidly-Exploring Random Trees (RRTs) have been successful at finding feasible solutions for many types of problems. With motion planning becoming more computationally demanding, we turn to parallel motion planning for efficient solutions. Existing work on distributed RRTs has been limited by the overhead that global communication requires.

Studi Performansi Algoritma Perencanaan Jalur diantara PRM, RRT, RRT* dan Informed-RRT
Telekontran : Jurnal Ilmiah Telekomunikasi, Kendali dan Elektronika Terapan, 2020 This paper will discuss a comparative performance review of several path planning algorithms. This study compares five well-known path planning algorithms, namely the Probabilistic Roadmap (PRM), Rapidly-exploring Random Tree (RRT), RRT* and Informed-RRT* algorithm. Testing is done through simulation based experiments using python.

Asymptotically near-optimal RRT for fast, high-quality, motion planning [PDF]
, 2015 We present Lower Bound Tree-RRT (LBT-RRT), a single-query sampling-based algorithm that is asymptotically near-optimal. Namely, the solution extracted from LBT-RRT converges to a solution that is within an approximation factor of 1+epsilon of the optimal

A small-scale study on airborne transmission of H9N2 avian influenza virus under field conditions
Journal of Infection in Developing Countries, 2018 Introduction: H9N2 avian influenza viruses (AIV) can transmit in chicken flocks through direct contact and aerosols. Nevertheless, data on airborne transmission of AIV is very limited, especially under field conditions. To fill this literature gap, this
