This paper presents a distributed algorithm in the CONGEST model that
achieves a
(1+ϵ)-approximation for row-sparse fractional covering
problems (RS-FCP) and the dual column-sparse fraction packing problems
(CS-FPP). Compared with the best-known
(1+ϵ)-approximation CONGEST
algorithm for RS-FCP/CS-FPP developed by Kuhn, Moscibroda, and Wattenhofer
(SODA'06), our algorithm is not only much simpler but also significantly
improves the dependency on
ϵ.
