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