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