We focus our interest on sparse and efficient preconditioners. In order to define the preconditioners, we perform two steps: first we reorder the unknowns and ...
We study two preconditioners based on the Repeated. Red-Black ordering. The second preconditioner corresponds to the one investi- gated by Brand and Heinemann.
The red-black ordering is to order the red nodes before the black nodes. Note that red nodes are adjacent to only black nodes. So if we update all the red ...
