The advantages of the proposed algorithm is that it is easy to use and
implement for a fast check. For sharp system it may provide quickly
solutions with a reasonable accuracy. The drawback is
that it may provide solutions intervals which does not
contain roots or, worse, miss some roots if `Dist` is not set to 0
(see section 2.3.5.2).

This algorithm may be used also for analysis: if we have to solve
numerous systems we may use this algorithm with a low `M` in order
to fast check if the current system may have some real roots, in which
case we may consider using a more sophisticated algorithm.

This solving algorithm may be tested on-line on the web page `ALIAS-on-line` that can be found on the COPRIN web page.
