Perhaps you should try some spelling variations:
"_ optimizer algorithmss" » "_ optimizer algorithms", "_ optimized algorithms"
"qoe estimation algorithms" » "qoe estimation algorithm", "qoe optimization algorithms", "qoe optimisation algorithm", "pose estimation algorithms", "_ estimation algorithms", "cover estimations algorithms"
"_ optimized algorithm" » "_ optimized algorithms", "_ optimizer algorithms"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

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