| We deal with a recently proposed method of Chubanov [1], for solving linear homogeneous systems with positive variables. We use Nesterovchr('39')s excessive gap method in the basic procedure. As a result, the iteration bound for the basic procedure is reduced by the factor $nsqrt{n}$. The price for this improvement is that the iterations are more costly, namely $O(n^2 )$ instead of $O(n)$. The overall gain in the complexity hence becomes a factor of $sqrt{n}$. |
