Perhaps you should try some spelling variations:
quantization algorithms » estimation algorithms, optimization algorithms
passive quantization » adaptive quantization
optimized algorithm » optimized algorithms, optimizer algorithms
modified passive » modified adaptive
bi1 optimized » _ optimized
modified bi1 » modified _

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 bi1 optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive quantization algorithms ) or ( modified bi1 optimized algorithm ))*.
