摘要
In this paper we propose an algorithm for generating maximum weight independent sets in a circle graph, that is, for putting out all maximum weight independent sets one by one without duplication. The time complexity is O(n(3) + beta), where n is the number of vertices, beta output size, i.e., the sum of the cardinalities of the output sets. It is shown that the same approach can be applied for spider graphs and for circuiar-arc overlap graphs.
