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