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