Before revision:  This paper introduces a new 3-2/b(G)-approximation algorithm for the graph burning problem over general graphs  , where b(G) is the size of an optimal solution.
After revision:  This paper introduces a new 3-2/b(G)-approximation algorithm for the graph burning problem over general graphs . The approximation factor of this algorithm is 3-2/b(G) , where b(G) is the size of an optimal solution.
