3-approximation Algorithm for the Travelling Repairman Problem with Unit Time-windows
The travelling repairman problem (TRP) is a scheduling problem in which a repairman must visit locations to perform some task. Each location has a time window in which the repairman is allowed to arrive. The objective of this problem is to maximize the number of tasks performed. In this paper, we consider a special case in which all the locations are on a straight line, the tasks have no proces...
متن کاملSpeedup in the Traveling Repairman Problem with Unit Time Windows
The input to the unrooted traveling repairman problem is an undirected metric graph and a subset of nodes, each of which has a time window of unit length. Given that a repairman can start at any location, the goal is to plan a route that visits as many nodes as possible during their respective time windows. A polynomial-time bicriteria approximation algorithm is presented for this problem, gain...
متن کاملSpeedup in the Traveling Repairman Problem with Constrained Time Windows
A bicriteria approximation algorithm is presented for the unrooted traveling repairman problem, realizing increased profit in return for increased speedup of repairman motion. The algorithm generalizes previous results from the case in which all time windows are the same length to the case in which their lengths can range between l and 2. This analysis can extend to any range of time window len...

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولThe Complexity of the Travelling Repairman Problem
— In the travelling repairman problem (TRP) we are given a finite set of points and the travel times between any two ofthem, and wish to find the route through them which minimizes the sum of the delays for reaching each point. We consider the TRP when ail points are on the straight line, and give a polynomial-time algorithm for it. If we have deadlines (that is, bounds on the maximum delay for...
