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