Perhaps you should try some spelling variations:
"modified df optimisation algorithmssss" » "modified df optimisation algorithm", "modified df optimization algorithms", "modified _ optimisation algorithmssss", "modified _ optimization algorithmssss", "modified qoe optimization algorithmssss", "modified adam optimisation algorithmssss", "modified bi1 optimisation algorithmssss"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation algorithm"

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