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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified adaptive quantization algorithm ) or ( mobile learning convolution algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified adaptive quantization algorithm ) OR ( mobile learning convolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified adaptive quantization algorithm ) or ( mobile learning convolution algorithm ))*.
