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

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: "((((\"_ optimized algorithm\") OR (\"_ estimation algorithms\"))) OR (\"cover optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (((( _ optimized algorithm ) OR ( _ estimation algorithms ))) OR ( cover optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithm") OR ("_ estimation algorithms"))) OR ("cover optimisation algorithm"))*.
