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