Dynamically Pruned A * for Re-planning in Navigation Meshes
"... Abstract—Modern simulations feature crowds of AI-controlled agents moving through dynamic environments, with obstacles appearing or disappearing at run-time. A dynamic navigation mesh can represent the traversable space of such en-vironments. The A * algorithm computes optimal paths through the dual ..."

present Dynamically Pruned A * (DPA*), an extension of A * for re-planning optimal paths in dynamic navi-gation meshes. DPA * has similarities to adaptive algorithms that make the A * heuristic more informed based on previous queries. However, DPA * prunes the search using only the previous path and its
RHC for Vision-Based Navigation of a WMR in an Urban Environment
"... This paper presents a control strategy for the navigation of an autonomous vehicle through an unknown environment with a focus on real-time implementation. The task at hand is to navigate from an initial position to a predetermined goal through an unknown environment using vision as the primary sens ..."

Control (RHC) path planner which calculates dynamically feasible and locally optimal trajectories. The feasibility of the real-time implementation of this system for vehicle navigation is investigated using a Wheeled Mobile Robot (WMR) testbed with a future goal of implementation on a Micro Air Vehicle
Experimental Validation for CRFNFP Algorithm
"... Abstract—In 2010,we proposed CRFNFP[1] algorithm to enhance long-range terrain perception for outdoor robots through the integration of both appearance features and spatial contexts. And our preliminary simulation results indicated the superiority of CRFNFP over other existing approaches in terms of ..."

of accuracy, robustness and adaptability to dynamic unstructured outdoor environments. In this paper, we further study on the comparison experiments for navigation behaviors of robotic systems with different scene perception algorithms in real outdoor scenes. We implemented 3 robotic systems and repeated
IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY 1 High Performance Stereo Vision Designed for Massively Data Parallel Platforms
"... Abstract—Real-time stereo vision is attractive in many applications like robot navigation and 3D scene reconstruction. Data parallel platforms, e.g. GPU, is often used for real-time stereo, because most stereo algorithms involve a large portion of data parallel computations. In this paper, we propos ..."

Real-world applications of analog and digital evolvable hardware
- Evolutionary Computation, IEEE Transactions on
, 1999
"... Abstract — In contrast to conventional hardware where the structure is irreversibly fixed in the design process, evolvable hardware (EHW) is designed to adapt to changes in task re-quirements or changes in the environment, through its ability to reconfigure its own hardware structure dynamically and ..."

QOS WITH RELIABILITY AND SCALABILITY IN ADAPTIVE SERVICE-BASED SYSTEMS
"... Service-based systems that are dynamically composed at runtime to provide complex, adaptive functionality are currently one of the main development paradigms in software engineering. However, the Quality of Service (QoS) delivered by these systems remains an important concern, and needs to be manage ..."

A Dynamic Path Planner For Autonomous Vehicles
, 1995
"... This paper proposes a method for the design of a dynamic path planner which utilizes fuzzy logic for navigation of mobile robots in uncertain environments. The method consists in identifying a dynamical system, with a fuzzy logic controller structure, from the examples generated by an "exper ..."

mapping is found by identifying a set of fuzzy rules from desired input-output data pairs. It is wanted with this idea to use the optimality qualities that the geometrical path planners have, integrating them in an sensor-based architecture, better adapted for the real-time specifications
