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