- W2895840401 abstract "The minimum <inline-formula xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink> <tex-math notation=LaTeX>$k$ </tex-math></inline-formula> -dominating set (MKDS) problem, a generalization of the classical minimum dominating set problem, is an important NP-hard combinatorial optimization problem with various applications. First, to alleviate the cycling problem in the local search, a MKDS two-level configuration checking (MKDSCC <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> ) strategy is presented. Second, we use the vertex cost scheme to define the scoring mechanism and to improve the solution effectively. Third, by combining MKDSCC <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> strategy and the scoring mechanism, we propose a vertex selection strategy to decide which vertex should be added into or removed from the candidate solution. Based on these strategies, an efficient local search algorithm (VSCC <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> ), which incorporates a two-level configuration checking strategy, scoring mechanism, and vertex selection strategy, is proposed. We compare the performance of VSCC <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> with the classic GRASP algorithm and the famous commercial solver CPLEX on the classical instances. The comprehensive results show that the VSCC <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>2</sup> algorithm is very competitive in terms of solution quality and computing time." @default.
