A kernel of order 2k-c log k for vertex cover
City University of New York.
2011 (English)In: Information Processing Letters, ISSN 0020-0190, E-ISSN 1872-6119, Vol. 111, no 23-24, 1089-1091 p.Article in journal (Refereed) Published
Abstract [en]

In a recent paper Soleimanfallah and Yeo proposed a kernelization algorithm for vertex cover which, for any fixed constant c, produces a kernel of order 2k - c in polynomial time. In this paper we show how their techniques can be extended to improve the produced kernel to order 2k - c log k, for any fixed constant c.
