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

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