Abstract

It was open for many years whether MinW-CDS in unit disk graphs has a polynomial-time constant-approximation or not. Ambühl et al. [2] discovered the first one. Their solution consists of two stages. At the first stage, they construct a dominating set which is a 72-approximation for the minimum-weight dominating set problem in unit disk graphs as follows.
