\begin{abstract}
Based on a coarsening strategy of adjacency matrix, a new algebraic
prolongation operator is developed for standard V-cycle multigrid method
to accelerate the whole process. An efficient algebraic multigrid (EAMG)
method is proposed for solving large-scale linear systems, arising from
finite element (FE) discretization of second order elliptic boundary
value problems. Numerical experiments on polygonal domains are conducted
to demonstrate the EAMG computation is more efficient than standard
method.%
