The directed chinese postman problem

H Thimbleby - Software: Practice and Experience, 2003 - Wiley Online Library
Abstract The Chinese Postman Problem has many applications, including robot exploration,
and analysing interactive system and Web site usability. This paper reviews the wide range …

Frequency estimation of internet packet streams with limited space

ED Demaine, A López-Ortiz, JI Munro - European Symposium on …, 2002 - Springer
We consider a router on the Internet analyzing the statistical properties of a TCP/IP packet
stream. A fundamental difficulty with measuring trafic behavior on the Internet is that there is …

Exploring unknown environments

S Albers, MR Henzinger - SIAM Journal on Computing, 2000 - SIAM
We consider exploration problems where a robot has to construct a complete map of an
unknown environment. We assume that the environment is modeled by a directed, strongly …

[PDF][PDF] The power of a pebble: Exploring and map** directed graphs

MA Bender, A Fernández, D Ron, A Sahai… - Proceedings of the …, 1998 - dl.acm.org
In thin paper we show:(1) If the robot knows an upper bound on the number of vertices then
it can learn the graph afilcicntly with only one pebble.(2) If the robot does not know nn upper …

Exploring unknown undirected graphs

P Panaite, A Pelc - Journal of Algorithms, 1999 - Elsevier
A robot has to construct a complete map of an unknown environment modeled as an
undirected connected graph. The task is to explore all nodes and edges of the graph using …

Graph exploration by a finite automaton

P Fraigniaud, D Ilcinkas, G Peer, A Pelc… - Theoretical Computer …, 2005 - Elsevier
A finite automaton, simply referred to as a robot, has to explore a graph whose nodes are
unlabeled and whose edge ports are locally labeled at each node. The robot has no a priori …

The power of team exploration: Two robots can learn unlabeled directed graphs

MA Bender, DK Slonim - Proceedings 35th Annual Symposium …, 1994 - ieeexplore.ieee.org
We show that two cooperating robots can learn exactly any strongly-connected directed
graph with n indistinguishable nodes in expected time polynomial in n. We introduce a new …

Collective tree exploration

P Fraigniaud, L Gasieniec… - Networks: An …, 2006 - Wiley Online Library
An n‐node tree has to be explored by k mobile agents (robots), starting at its root. Every
edge of the tree must be traversed by at least one robot, and exploration must be completed …

Tree exploration with little memory

K Diks, P Fraigniaud, E Kranakis, A Pelc - Journal of Algorithms, 2004 - Elsevier
A robot with k-bit memory has to explore a tree whose nodes are unlabeled and edge ports
are locally labeled at each node. The robot has no a priori knowledge of the topology of the …

Multirobot tree and graph exploration

P Brass, F Cabrera-Mora, A Gasparri… - IEEE Transactions on …, 2011 - ieeexplore.ieee.org
In this paper, we present an algorithm for the exploration of an unknown graph by multiple
robots, which is never worse than depth-first search with a single robot. On trees, we prove …
