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