Perhaps you should try some spelling variations:
"modified df optimisation algorithmss" » "modified df optimisation algorithm", "modified df estimation algorithms", "modified df estimation algorithm", "modified _ optimisation algorithmss", "modified _ optimization algorithmss", "modified qoe optimization algorithmss", "modified adam optimisation algorithmss", "modified bi1 optimisation algorithmss"
"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 df optimisation algorithmss") or ("modified objective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df optimisation algorithmss") OR ("modified objective optimization algorithms")).
• Removing quotes may allow a broader search: (( modified df optimisation algorithmss ) or ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified df optimisation algorithmss") or ("modified objective optimization algorithms"))*.
