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