Perhaps you should try some spelling variations:
"qoe optimisation algorithms" » "qoe optimisation algorithm", "qoe optimization algorithms", "qoe estimation algorithms", "_ optimisation algorithms", "game optimization algorithms"
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimized algorithm") OR ("_ optimization algorithm"))) OR ("qoe optimisation algorithms"))~.
• Removing quotes may allow a broader search: (((( _ optimized algorithm ) or ( _ optimization algorithm ))) or ( qoe optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithm") or ("_ optimization algorithm"))) or ("qoe optimisation algorithms"))*.
