Perhaps you should try some spelling variations:
quantization algorithms » estimation algorithms
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
adaptive quantization » adaptive ventilation
modified adaptive » modified passive
near optimization » network optimization, stage optimization, _ optimization
modified near » modified seird, 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 adaptive quantization algorithms ) OR ( modified near optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive quantization algorithms ) or ( modified near optimization algorithms ))*.
