Perhaps you should try some spelling variations:
"qoe optimization algorithms" » "qoe optimisation algorithm", "qoe estimation algorithms", "qoe estimation algorithm", "game optimization algorithms", "_ optimization algorithms", "stage optimization algorithms"
"qoe optimized algorithms" » "qoe optimized algorithm", "qoe optimizer algorithms", "_ optimized algorithms"
"_ optimize algorithmss" » "_ optimizer algorithms", "_ optimized algorithm", "_ optimized algorithmss", "_ optimise algorithmss"

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

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