It may be interesting to stop the solving procedures although the algorithm has not been completed. We have already seen that a possible mean to do that was to specify a number of roots in such way that the procedure will exit as soon it has found this number of roots.

Another possible way to stop the calculation is to use a time-out
mechanism. For that purpose you may define in the
double `ALIAS_TimeOut` the maximum number of minutes allowed for the
calculation. If this number is reached (approximatively) the procedure
will exit and will set the flag
`ALIAS_TimeOut_Activated` to 1.

The solution that have been found by the algorithms are stored in the
interval matrix `ALIAS_Solution` and their number is
`ALIAS_Nb_Solution`.
Note that for the procedures involving the Jacobian this matrix will
usually describes the boxes that include a unique solution.
