<BLOCKQUOTE>"Quadratic Constrained Machine".
It's a machine with <TT>alpha</TT> parameters which
are the minimum of a constrained quadratic problem.
<P>The problem:
<P>minimize <IMG BORDER=0 SRC=g000022.gif>
<P>with the following constraints:
<UL>
<LI> <IMG BORDER=0 SRC=g000023.gif>
<LI> <IMG BORDER=0 SRC=g000024.gif>
</UL>
<P>where <IMG BORDER=0 SRC=g000025.gif>, <IMG BORDER=0 SRC=g000026.gif>, <IMG BORDER=0 SRC=g000027.gif> are given by the user
and <IMG BORDER=0 SRC=g000028.gif>.
<P>The number of <TT>alpha</TT> variable is determined here by <TT>l</TT>.
(Therefore, it determines the size of de Cup, Cdown et y...)
<P>Note: if <IMG BORDER=0 SRC=g000029.gif> is closed to <IMG BORDER=0 SRC=g000030.gif> [ou <IMG BORDER=0 SRC=g000031.gif>] with
the accuracy "eps bounds", <IMG BORDER=0 SRC=g000029.gif> is considered
to be equal to <IMG BORDER=0 SRC=g000030.gif> [ou <IMG BORDER=0 SRC=g000031.gif>].
<P>Options:
<TABLE BORDER>
<TR><TD>
"eps bounds" </TD><TD> real </TD><TD> bound accuracy: </TD><TD> [1E-4 in float, 1E-12 in double]
