Perhaps you should try some spelling variations:
"modified qoe optimization algorithmssss" » "modified qoe optimization algorithms", "modified qoe optimisation algorithm", "modified qoe optimization algorithmsssss", "modified qoe optimisation algorithmssss", "modified qoe estimation algorithmssss", "modified game optimization algorithmssss", "modified _ optimization algorithmssss", "modified stage optimization algorithmssss", "modified male optimization algorithmssss", "modified bi1 optimization algorithmssss"
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimization algorithm") OR ("modified qoe optimization algorithmssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective optimization algorithm\") OR (\"modified qoe optimization algorithmssss\"))".
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithm ) OR ( modified qoe optimization algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithm") OR ("modified qoe optimization algorithmssss"))*.
