Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"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.

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