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

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