This paper is concerned with on-line problems where a mobile robot of size D has to achieve a task in an unknown planar environment whose geometry is acquired by the robot during task execution. ...
Given an on-line task, its competitive complexity class is a pair of lower and upper bounds on the competitive performance of all on-line algorithms for the task, such that the two bounds satisfy the same ...
For example, in the on-line navigation problem a disconnection proof would be a detection that the target is unreachable from the start point. ...
