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