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

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

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