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