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