Perhaps you should try some spelling variations:
"modified adam optimisation algorithmssssss" » "modified adam optimisation algorithm", "modified _ optimisation algorithmssssss", "modified game optimization algorithmssssss", "modified df optimisation algorithmssssss", "modified near optimisation algorithmssssss"
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"

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: (("modified objective optimization algorithms") or ("modified adam optimisation algorithmssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimization algorithms") OR ("modified adam optimisation algorithmssssss")).
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) or ( modified adam optimisation algorithmssssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") or ("modified adam optimisation algorithmssssss"))*.
