Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified write optimization algorithmss" » "modified write optimization algorithms", "modified write optimisation algorithm", "modified write estimation algorithm", "modified game optimization algorithmss", "modified qoe optimization algorithmss", "modified stage optimization algorithmss"

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