abstract = {<p style="text-align: justify;">A greedy Gauss-Seidel based on the greedy Kaczmarz algorithm and aimed
to find approximations of the solution $A^†b$ of systems of linear algebraic equations with
a full column-rank coefficient matrix $A$ is proposed. Developing this approach, we introduce a partially greedy randomized extended Gauss-Seidel method for finding approximate least-norm least-squares solutions of column-rank deficient linear systems. The
convergence of the methods is studied. Numerical experiments show that the proposed
methods are robust and efficient.</p>},
