In combinatorial optimization, a popular approach to NP-hard problems is the design of approximation algorithms. These algorithms typically run in polynomial time and are guarante...
Abstract. We explore techniques for efficient Quality of Service Routing in the presence of multiple constraints. We first present a polynomial time approximation algorithm for th...
This paper presents a novel discrete population based stochastic optimization algorithm inspired from weed colonization. Its performance in a discrete benchmark, timecost trade-off...
In this paper, we introduce the generalized capacitated tree-routing problem (GCTR), which is described as follows. Given a connected graph G = (V, E) with a sink s V and a set M...
The route guidance system, which provides driving advice based on traffic information about an origin and a destination, has become very popular along with the advancement of hand...
