Concurrent multipath transfer (CMT) can improve data throughput, bandwidth resource utilization and system robustness. Whereas, CMT also leads to serious reordering problem, especially in heterogeneous wireless networks. Since more than one path are used, an efficient CMT scheduling algorithm is needed at the sender. For existing packet scheduling, packet's rate of entering the sender queue is usually...
Algorithmic self-assembly, a generalization of crystal growth, has been proposed as a mechanism for the bottom-up fabrication of autonomous DNA computation. In theory, growth can be programmed by designing a set of molecular tiles with binding interactions that enforce assembly rules. There are many interesting applications of the reordering problem in Mathematics, as well as Computer Sciences. It...
We present a new implementation of a widely used swap-based local search procedure for the p-median problem, proposed in 1968 by Teitz and Bart. Our method produces the same output as the best alternatives described in the literature and, even though its worst-case complexity is similar, it can be significantly faster in practice: speedups of up to three orders of magnitude were observed. We also...
