This paper addresses the navigation problems facing many companies, including logistics couriers, and Uber, helping users find best route to multiple destinations in shortest amount of time. Navigation involving are formulated this as Directed Steiner Tree (DST) on directed graphs. We propose an end-to-end deep learning approach tackle DST a supervised non-autoregressive manner. The core our is...

Cataglyphis ants are renowned for their impressive navigation skills, which have been studied in numerous experiments during forward locomotion. However, the ants' navigational performance during backward homing when dragging large food loads has not been investigated until now. During backward locomotion, the odometer has to deal with unsteady motion and irregularities in inter-leg coordinatio...

Messengers are autonomous objects, each capable of navigating through the underlying network and performing various tasks at each node. Messengers applications are written using navigational commands rather than the send/receive primitives of conventional message-passing approaches. In this paper we contrast the two programming styles. The navigational style generally results in a smaller seman...

|This research concerns e cient multiprocessor threads-based implementation of reactive navigation for mobile robots. We present two important results: 1) Performance is improved signi cantly when CPU time allocated to individual navigational threads is adjusted dynamically according to a heuristic measure of their importance. 2) To implement this strategy, we present a multiprocessor scheduler...

In this paper we present a novel approach for defining hypermedia applications as navigational views of an object-oriented hypermedia schwma. We briefly describe OOHDM (Object-Oriented Hypermedia Design Model) using an academic information system as a concrete example to illustrate each modeling construct. We further analyze the whole process of hypermedia applications building focusing mainly ...

A core set of navigational aspects may be found by extracting the key features of hypermedia applications. Incorporated to an information system (IS), they may increase its utility and usability (1). This type of extension of an IS is called ‘The Hypertext Functionality Approach’ (2), and it may be done in different ways. In this paper we present a novel approach to add navigational features in...
