Let L(a
M) be a n-dimension integer lattice associated with the subset sumproblem
=M. It is proved that every version of the L3-algorithm in [1
2
3] working on the L(a
M) can be actually executed at most only in O(*)/n bit operations
where O(*) is the upper bound for processing a general integer lattice with the same scale by using the algorithm[l

3]. Then
some results about the condition and the success rate of using the algorithm mentioned above are given.
