“…An overview of successful methods for solving (single-objective) set covering problems is given by Caprara, Toth, and Fischetti (2000) and Umetani and Yagiura (2007). In particular, the 3-flip neighborhood search heuristic proposed by Yagiura, Kishida, and Ibaraki (2006) and the multi-start heuristic Meta-RaPS of Lan, DePuy, and Whitehouse (2007) have proven superior to previous approaches. Furthermore, the Bi-objective Set Covering Problem (BOSC) investigated by Jaszkiewicz (2004) and Prins, Prodhon, and Calvo (2006) shows similarities to the 2WDP-SC; however, the BOSC differs in the objective function f 2 .…”
