Given a graph whose arc traversal times vary over time, the Time‐Dependent Travelling Salesman Problem consists of finding a Hamiltonian tour of least total duration. In this paper we exploit some properties of the problem and develop a branch‐and‐bound algorithm which outperforms the state‐...
Branch-and-bound algorithm for reverse top-k queries 来自 Semantic Scholar 喜欢 0 阅读量: 62 作者:A Vlachou,C Doulkeridis,Kjetil Nrvg,Y Kotidis 摘要: Top-k queries return to the user only the k best objects based on the individual user preferences and comprise an essential tool for rank...
This problem is formulated as a mixed integer programme, and a branch and bound algorithm is presented for its solution. The structural properties of this programming problem are discussed, which con be used to improve the computational efficiency of our branch and bound algorithm. An illustrative ...

We present a branch-and-bound algorithm for solving the p -median problem. The bounds are obtained by solving the Lagrangian relaxation of the p -median problem using the subgradient optimization method. The proposed algorithm is simple, requires small core storage and computational time, and can...
We describe a branch-and-bound algorithm for solving the general version of the problem based on its image space representation. The suggested approach specifically addresses the difficulties arising in the case when the number of ratios exceeds two. The efficacy of our approach is demonstrated on ...
