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