Perhaps you should try some spelling variations:
quantization algorithms » estimation algorithms, optimization algorithms
approximation algorithm » approximation algorithms
adaptive quantization » adaptive ventilation
time approximation » one approximation, _ approximation
modified adaptive » modified passive
modified time » modified bi1, modified male

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( modified time approximation algorithm ) OR ( modified adaptive quantization algorithms ))~.
