Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
quantization algorithm » estimation algorithm
adaptive quantization » adaptive ventilation
near optimization » network optimization, stage optimization, _ optimization
modified adaptive » modified passive
modified near » modified seird, modified adam

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified near optimization algorithms ) or ( modified adaptive quantization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified near optimization algorithms ) OR ( modified adaptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified near optimization algorithms ) or ( modified adaptive quantization algorithm ))*.
