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