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

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ optimized algorithms") or ((("qoe estimation algorithm") or ("game estimation algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ optimized algorithms") OR ((("qoe estimation algorithm") OR ("game estimation algorithms")))).
• Removing quotes may allow a broader search: (( _ optimized algorithms ) or ((( qoe estimation algorithm ) or ( game estimation algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithms") or ((("qoe estimation algorithm") or ("game estimation algorithms"))))*.
