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