<Para ID="Par1">Recently, a walk-and-round heuristic was proposed by Huang and Mehrotra (Comput Optim Appl, <CitationRef CitationID="CR24">2012</CitationRef>) for generating high quality feasible solutions of mixed integer linear programs. This approach uses geometric random walks on a polyhedral set to sample points in this set. It subsequently rounds...</citationref></para>

Feasibility pump is a general purpose technique for finding feasible solutions of mixed integer programs. In this paper we report our computational experience on using geometric random walks and a random ray approach to provide good points for the feasibility pump. Computational results on <Emphasis...</emphasis>

In recent years, many firms have become aware that environmental issues are critical barriers to the sustainability of a business. To overcome these barriers, several studies have been conducted to develop quantitative measurements associated with industry practices to prevent pollution and...

This paper considers a real-life identical parallel scheduling problem originating from the manufacturing plant producing polyvinyl chloride leather products. In the considered scheduling problem, each job has some attributes and each attribute has several different levels. Because there is at...
