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