Perhaps you should try some spelling variations:
quantization algorithm » estimation algorithm
passive quantization » adaptive quantization
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified passive » modified adaptive
modified sales » modified male, modified traces
sales solution » sales evolution, saline solution, water solution

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