Approximation algorithms for multiconstrained quality-of-service routing
Meongchul Song, Sartaj K. Sahni · IEEE Transactions on Computers · 2006
We propose six new heuristics to find a source-to-destination path that satisfies two or more additive constraints on edge weights. Five of these heuristics become /spl epsi/-approximation algorithms when their parameters are appropriately set. The performance of our new heuristics is compared experimentally with that of two recently proposed heuristics for the same problem.
