Perhaps you should try some spelling variations:
"some optimizer algorithms" » "some optimized algorithms", "some optimization algorithms"
"game optimized algorithm" » "game optimized 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.

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