Perhaps you should try some spelling variations:
_damdaptive quantization » adaptive quantization
quantization algorithm » estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
modified _damdaptive » modified adaptive
3d estimation » _ estimation
modified 3d » modified _, modified df, modified adam

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified _damdaptive quantization algorithm ) OR ( modified 3d estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified _damdaptive quantization algorithm ) or ( modified 3d estimation algorithms ))*.
