/Filter /FlateDecode In this work, we deal with the Budgeted Maximum Coverage Problem (BMCP), which is a generalized 0-1 knapsack problem.

>> Note that there are different versions of maximum coverage problem such as weighted and/or budgeted maximum coverage problems. In this paper we show that a simple greedy algorithm gives a constant fac-tor approximation for both the cardinality and the cost versions of MCG. (Inf. ͳ� xH�f/!�fH�̃�ȒL� ���Q ����t�Go��F�-�lϋ��2-D.�Fb���Db8�4� Lett., 1999), our problem is fundamentally different from an algorithmic point of view, due to its cost structure. 2 Maximum Coverage In this section, we will cover unweighted maximum coverage problem. Knapsack problems are classic models that can formulate a wide range of applications. Contents 1 Introduction 2 2 Literature 3 3 The Maximum Coverage Problem5 The budgeted maximum coverage problem.

Theory of computation. Logic. 51 0 obj The contributions of this paper are as follows: (i)The partial vertex cover and budgeted maximum coverage problems are NP-hard on bipartite graphs. The difference of our problem to the budgeted maximum coverage problem is that the costs are associated with the covered vertices instead of the selected hyperedges. xڅWKs�6��W�H΄,�7:�C҉���4v��[email protected]",cB�*@�v}����L/�X,���v��&H���ҳ�W�W�]�:E�U��B�I�7A-�n��S��*��\�u�ٛ��ΌO�i8���m�e��F_na�"�eIf�ĢN���`�f}?��p�c����[�vޢ\�k��Y�y���b���:���^w�Y��kg�ٞ-�I���w�(���j4C��?h��e�!x��� ��"��4�*������w�h�Q.�i˂�(��=����W{o�U�1[x�@��"�3��h����^��lTT��h� ���ng1����~y��r���>�wQ��"�� ��FE��ѝfa� ] �^��!/��=�Ӂ

For the budgeted maximum coverage problem, the relaxation-based tabu swap local search algorithm performs best, but has a longer runtime than existing greedy and local search algorithms. to the budgeted maximum coverage problem considered by Khuller et al. We will cover only unweighted case. It is easily seen that this problem is strictly harder than budgeted max coverage, which means that the problem is (1 - 1/e)-inapproximable. Comments.

/Length 1763 In MC, the input is a number L, a set of elements E, and a collection C of subsets of E. The new problem is related to three known problems: the Maximum Coverage Problem (MC) [4], the Budgeted Maximum Coverage Problem (BMC) [6], and the Multiple Choice Knapsack Problem (MCKP) [5] (see Figure 1).
