ScienceDirect Publication: Computers & Operations Research
Publication date: Available online 14 April 2018 Source:Computers & Operations Research Author(s): Martina Fischetti, Marco Fraccaro In this paper we propose a combination of Mathematical Optimization and Machine Learning to estimate the value of optimized solutions. In particular, we investigate if a machine, trained on a large number...
Publication date: May 2018 Source:Computers & Operations Research, Volume 93 Author(s): Shahrzad M. Pour, John H. Drake, Edmund K. Burke A new signalling system in Denmark aims at ensuring fast and reliable train operations. However, it imposes very strict time limits on recovery plans in the event of failure. As a result, it is necessary...
Publication date: Available online 11 April 2018 Source:Computers & Operations Research Author(s): Francisco Salas-Molina Organizations use cash management models to control balances to both avoid overdrafts and obtain a profit from short-term investments. Most management models are based on control bounds which are derived from the assumption...
Publication date: July 2018 Source:Computers & Operations Research, Volume 95 Author(s): Ankur Sinha, Pekka Malo, Markku Kallio Many objective optimization problems have turned out to be a considerable challenge for evolutionary algorithms due to the difficulty of finding and visualizing high-dimensional Pareto frontiers. Fortunately,...
Publication date: May 2018 Source:Computers & Operations Research, Volume 93 Author(s): Christian Tilk, Stefan Irnich This paper considers the exact solution of the optimal communication spanning tree problem (OCSTP), which can be described as follows: Given an undirected graph with transportation costs on every edge and communication requirements...
Publication date: July 2018 Source:Computers & Operations Research, Volume 95 Author(s): Shunji Tanaka, Fumitaka Mizuno The purpose of this study is to propose an exact algorithm for the unrestricted block relocation problem with distinct priorities. In this problem, a storage area is considered where blocks of the same size are stacked...
