A Comparative Study of Meta-heuristic Algorithms for Solving Quadratic Assignment Problem

Author 1: Gamal Abd El-Nasser A. Said Author 2: Abeer M. Mahmoud Author 3: El-Sayed M. El-Horbaty

Quadratic Assignment Problem (QAP) is an NP-hard combinatorial optimization problem, therefore, solving the QAP requires applying one or more of the meta-heuristic algorithms. This paper presents a comparative study between Meta-heuristic algorithms: Genetic Algorithm, Tabu Search, and Simulated annealing for solving a real-life (QAP) and analyze their performance in terms… Read full abstract & cite →

On A New Competitive Measure For Oblivious Routing

Author 1: Gábor Németh

Oblivious routing algorithms use only locally avail¬able information at network nodes to forward traffic, and as such, a plausible choice for distributed implementations. It is a natural desire to quantify the performance penalty we pay for this distributedness. Recently, Räcke has shown that for general undirected graphs the competitive ratio… Read full abstract & cite →
