Perhaps you should try some spelling variations:
quantization algorithm » estimation algorithm
passive quantization » adaptive quantization
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
learning solution » learning convolution, learning emotion
modified passive » modified adaptive
mobile learning » machine learning

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