Perhaps you should try some spelling variations:
quantization algorithm » estimation algorithm
passive quantization » adaptive quantization
solutions algorithm » solution algorithm, evolution algorithm, evolutionary algorithm
modified passive » modified adaptive
mild solutions » time solutions
modified mild » modified male, modified seird, 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 passive quantization algorithm ) OR ( modified mild solutions algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified passive quantization algorithm ) or ( modified mild solutions algorithm ))*.
