Perhaps you should try some spelling variations:
"_ optimization algorithms" » "_ optimisation algorithm", "_ estimation algorithms", "_ optimized algorithms"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"_ optimization algorithms\") OR (\"qoe optimized algorithm\"))) OR (\"qoe estimation algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ optimization algorithms ) OR ( qoe optimized algorithm ))) OR ( qoe estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimization algorithms") OR ("qoe optimized algorithm"))) OR ("qoe estimation algorithm"))*.
