Approximation Algorithm of Minimum All-Ones Problem for Arbitrary Graphs

Chen Wang, Chao Wang, Gregory Z. Gutin +1

Let $G = (V, E)$ be a graph and let each vertex of $G$ has a lamp and a button. Each button can be of $I ¨ ^{+}$ -type or $I ¨ $ -type. Assume that initially some lamps are on and others are…
