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