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