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

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: "((((\"_ optimizer algorithms\") OR (\"_ estimation algorithms\"))) OR (\"qoe optimization algorithms\"))~".
• Removing quotes may allow a broader search: (((( _ optimizer algorithms ) OR ( _ estimation algorithms ))) OR ( qoe optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimizer algorithms") OR ("_ estimation algorithms"))) OR ("qoe optimization algorithms"))*.
