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

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 optimization algorithm") OR ("modified write optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"modified write optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified write optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("modified write optimization algorithms"))*.
