Exact and approximation algorithms for joint routing and flow rate optimization

Junosza-Szaniawski Konstanty, Nogalski Dariusz

Annals of Computer Science and Information Systems

2019

Vol. 20

29--36

This paper addresses comparison of algorithms for a version of the NUM problem. The joint formulation of routing and transmission rate control within the multi-user and single-path setting is assumed within the NUM. Since problem is NP-hard, the efficient heuristics are designed, implemented and compared experimentally with other existing heuristics and exact linear programming solver. The linear approximation is applied for nonlinear utility function. The results of experiments demonstrate a trade-off between computing time and precision of goal value.
