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

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("enabling learning aided algorithm") or ("modified multiobjective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("enabling learning aided algorithm") OR ("modified multiobjective optimization algorithms")).
• Removing quotes may allow a broader search: (( enabling learning aided algorithm ) or ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("enabling learning aided algorithm") or ("modified multiobjective optimization algorithms"))*.
