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