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 estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

You may be able to get more results by adjusting your search query.

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