**Anmerkung.**
|
||||
Bei Quicksort konnten wir sehen, dass die Zeit- (und Satzbewegungs!) komplexität durch
|
||||
$C(n) = 2C(n/2) + Θ(n)$ gegeben ist (warum diese Koeffizienten, warum Θ(n)?).
|
||||
</br>
|
||||
Laut **Mastertheorem** gilt also $C(n) ∈ Θ(n·log(n))$ (warum?).
|
||||
</br>
|
||||
Das ist aber der Worst-case.
|
||||
</br>
|
||||
Wie verhält sich das beim Average-Case ($C_{av}(n)$)?

Aspekte und Berechnungen mit binären Suchbäumen
|
||||
|
||||
-
|
||||
- Aspekte, insbesondere *ausgeglichen*.
|
||||
- Motivation: wieso wollen wir *ausgeglichene* Suchbäume?
|
||||
- Optimierung der Tiefe h vis-á-vis Anzahl der Knoten, n.
|
||||
- Suchalgorithmus im Suchbaum
|
||||
- welche Verhältnisse müssen zw. den Knoten gelten?
|
||||
- Ansatz bei INSERT und ROTATE, um *ausgeglichenen* Baum
|
||||
mit passenden Verhältnissen zw. Knoten zu erzeugen.
