Perhaps you should try some spelling variations:
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"
"mapping learning aided algorithm" » "machine learning aided algorithm", "enabling learning aided algorithm", "mapping learning adam algorithm", "mapping learning driven algorithm", "mapping learning winner algorithm", "mapping learning based algorithm", "mapping learning model algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("mapping learning aided algorithm") OR ("modified objective estimation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"mapping learning aided algorithm\") OR (\"modified objective estimation algorithm\"))".
• Removing quotes may allow a broader search: (( mapping learning aided algorithm ) OR ( modified objective estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning aided algorithm") OR ("modified objective estimation algorithm"))*.
