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