BIRD-VNE: Backtrack-avoidance virtual network embedding in polynomial time
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)The virtual network embedding (VNE) problem is known to be NP-hard, and as a result, several heuristic approaches have been proposed to solve it. These heuristics find sub-optimal solutions in polynomial time, but have ... -
