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