Perhaps you should try some spelling variations:
"qoe optimization algorithms" » "qoe optimisation algorithm", "qoe estimation algorithm", "qoe optimizer algorithms", "game optimization algorithms", "_ optimization algorithms", "stage optimization algorithms"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimisation algorithm", "_ approximation algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer 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: "((\"_ optimized algorithms\") OR (((\"qoe optimization algorithms\") OR (\"_ estimation algorithms\"))))~".
• Removing quotes may allow a broader search: (( _ optimized algorithms ) OR ((( qoe optimization algorithms ) OR ( _ estimation algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithms") OR ((("qoe optimization algorithms") OR ("_ estimation algorithms"))))*.
