Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
notion optimization » network optimization, policy optimization, allocation optimization
mobile learning » machine learning
a algorithm » _ algorithm, _ algorithms, adam algorithm
learning a » 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 notion optimization algorithms ) OR ( mobile learning a algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified notion optimization algorithms ) OR ( mobile learning a algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified notion optimization algorithms ) OR ( mobile learning a algorithm ))*.
