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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified passive quantization algorithm ) OR ( modified learning convolution algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive quantization algorithm ) OR ( modified learning convolution algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified passive quantization algorithm ) OR ( modified learning convolution algorithm ))*.
