Perhaps you should try some spelling variations:
quantization algorithms » estimation algorithms, optimization algorithms
passive quantization » adaptive quantization
modified learning » mobile learning, modified caging
emotion algorithm » evolution algorithm, estimation algorithm, predation algorithm
modified passive » modified adaptive
learning emotion » learning method

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 algorithms ) OR ( modified learning emotion algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive quantization algorithms ) OR ( modified learning emotion algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified passive quantization algorithms ) OR ( modified learning emotion algorithm ))*.
