Perhaps you should try some spelling variations:
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithm"
"_ estimation algorithms" » "_ estimation algorithm", "_ optimization algorithms", "_ optimisation algorithm"
"qoe optimized algorithm" » "qoe optimized algorithms", "qoe optimizer algorithms", "_ optimized 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: "((((\"_ estimation algorithms\") OR (\"qoe optimized algorithm\"))) OR (\"_ optimization algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ estimation algorithms ) OR ( qoe optimized algorithm ))) OR ( _ optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ estimation algorithms") OR ("qoe optimized algorithm"))) OR ("_ optimization algorithm"))*.
