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

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 ("model learning emotion algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion optimization algorithms\") OR (\"model learning emotion algorithm\"))".
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) OR ( model learning emotion algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") OR ("model learning emotion algorithm"))*.
