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"
"_ optimize algorithmss" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimise algorithmss"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimised algorithm"

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