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