11.4.4 Future Challenges
The current technique considered only a limited number of index structures
and possible approximation models. Preliminary results suggest that simu-
lation time can be reduced further by allowing the algorithm to adaptively
change the regions and the function approximation models used in these re-
gions. This needs to be examined in-depth and for simulations from different
scientific domains. Another interesting direction for future work is to study
thoroughly the tradeoff between simulation time, error threshold, and approx-
imation quality observed in practice.
