| Abstract(in English) | Given a multiset A^^ over finite set U and colletion C(*⫅)2^U, Minimum Multiset Covering is the probiem to find a smallest subset C(*⫅)C that covers A^^. This problem is a natural extension of Minimum set Covering where U is extented to a multiset A^^. We Present a polynomial-time approximation algorithm for Minimum Multiset Covering, and prove that the algorithmguarantees an approximation ratio 1+In n with the total size n of A. Also we show that the algorithm can be extented with the similar ratio to one for the problem where cover can have multisets. |
