Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
quantization algorithm » estimation algorithm
adaptive quantization » adaptive ventilation
modified adaptive » modified passive
df optimization » _ optimization, qoe optimization, _ optimisation
modified df » modified _, modified adam, modified bi1

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 df optimization algorithms ) OR ( modified adaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified df optimization algorithms ) or ( modified adaptive quantization algorithm ))*.
