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

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