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