摘要：
In the present work we combine the Lanczos algorithm and the lowest order constrained variational method (LOCV) to obtain a simple version of the Lanczos algorithm. In order to test the method the ground state energy and the antisymmetric mass gap of the U(1) lattice gauge model are calculated, and the results are compared with those computed by other many body methods.
