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