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