Perhaps you should try some spelling variations:
quantization algorithms » estimation algorithms, optimization algorithms
approximation algorithm » approximation algorithms
passive quantization » adaptive quantization
seird approximation » time approximation, network approximation
modified passive » modified adaptive
modified seird » modified near

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 passive quantization algorithms ) OR ( modified seird approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive quantization algorithms ) or ( modified seird approximation algorithm ))*.
