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