Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithms", "modified multiobjective estimation algorithmss"
"modified qoe optimization algorithm" » "modified qoe optimisation algorithm", "modified qoe estimation algorithm", "modified qoe estimation algorithms", "modified game optimization algorithm", "modified _ optimization algorithm", "modified stage optimization algorithm", "modified male optimization algorithm", "modified bi1 optimization 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 qoe optimization algorithm") OR ("modified multiobjective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified qoe optimization algorithm\") OR (\"modified multiobjective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified qoe optimization algorithm ) OR ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified qoe optimization algorithm") OR ("modified multiobjective optimization algorithms"))*.
