A variety of (one-level and multi-level) preconditioners can be obtained
by a suitable setting of the preconditioner parameters. These parameters
can be logically divided into four groups, i.e. parameters defining
<OL>
<LI>the type of multi-level preconditioner;
</LI>
<LI>the one-level preconditioner used as smoother;
</LI>
<LI>the aggregation algorithm;
</LI>
<LI>the coarse-space correction at the coarsest level.
</LI>
</OL>
A list of the parameters that can be set, along with their allowed and
default values, is given in Tables&nbsp;<A HREF="#tab:p_type"><IMG ALIGN="BOTTOM" BORDER="1" ALT="[*]"
SRC="file:/usr/share/latex2html/icons/crossref.png"></A>-<A HREF="#tab:p_coarse"><IMG ALIGN="BOTTOM" BORDER="1" ALT="[*]"
SRC="file:/usr/share/latex2html/icons/crossref.png"></A>.
For a detailed description of the meaning of the parameters, please
refer to Section&nbsp;<A HREF="node10.html#sec:background"><IMG ALIGN="BOTTOM" BORDER="1" ALT="[*]"
