Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
notion optimization » network optimization, policy optimization, allocation optimization
emotion algorithm » evolution algorithm, estimation algorithm, predation algorithm
learning emotion » learning method
code learning » how learning

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

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