Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization 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 multiobjective estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mapping learning aided algorithm") OR ("modified multiobjective estimation algorithm")).
• Removing quotes may allow a broader search: (( mapping learning aided algorithm ) or ( modified multiobjective estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mapping learning aided algorithm") or ("modified multiobjective estimation algorithm"))*.
