NOTE for persons interested in that algorithm: in the published version of this article, there are two (very little) typing errors, both on page 60:
* Section III.C. line 4 should say: “and $p_j^{(2)}$ the current point on $C^{(2)}$”.
* Section III.D. subsection “TRIANGULATION ALGORITHM” within Step A1 line 2 should say: “if additionally $x_{i+1}^{(1)} \leq x_{j+1}^{(2)}$ then $C^{(1)}$ provides the next point; …”.

!!! Important Note for persons interested in that ALGORITHM: in the published LNCS article version, there are two typing errors, both within the first lines of page 54:
* Line 3: instead of $O$ it should be $O_S$.
* Line 9: instead of $O$ it should be $O_E$.
In the pseudocode on page 57, everything is correct, in particular, $I_S$ and $I_E$ are well defined there. The error in the definitions of $I_S$ and $I_E$ appears only in the text. These errors were corrected for the arxiv-Version !
