TL;DR: Simple schemes are presented which are asymptotically slower, but have T/spl sime/3/spl middot/n for all n and Q between 2 and 8, and a near-optimal result is obtained.
Abstract: We consider the permutation routing problem on two-dimensional n/spl times/n meshes. To be practical, a routing algorithm is required to ensure very small queue sizes Q, and very low running time T, not only asymptotically but particularly also for the practically important n up to 1000. With a technique inspired by a scheme of Kaklamanis/Krizanc/Rao, we obtain a near-optimal result: T=2/spl middot/n+/spl Oscr/(1) with Q=2. Although Q is very attractive now, the lower order terms in T make this algorithm highly impractical. Therefore we present simple schemes which are asymptotically slower, but have T/spl sime/3/spl middot/n for all n and Q between 2 and 8. >

TL;DR: In this paper, the authors considered the permutation routing problem on two-dimensional n/spl times/n meshes and obtained a near-optimal result: T = 2/spl middot/n+/spl Oscr/(1) with Q = 2.
