Perhaps you should try some spelling variations:
"game optimization algorithms" » "game optimisation algorithm", "game estimation algorithms", "game optimized algorithms", "stage optimization algorithms", "qoe optimization algorithms", "market optimization algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer 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 algorithm") or ((("qoe estimation algorithm") or ("game optimization algorithms"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ optimized algorithm") OR ((("qoe estimation algorithm") OR ("game optimization algorithms")))).
• Removing quotes may allow a broader search: (( _ optimized algorithm ) or ((( qoe estimation algorithm ) or ( game optimization algorithms )))).
• Adding a wildcard symbol may retrieve word variants: (("_ optimized algorithm") or ((("qoe estimation algorithm") or ("game optimization algorithms"))))*.
