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