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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("qoe optimisation algorithm") OR ("_ optimisation algorithm"))) or ("_ estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe optimisation algorithm") OR ("_ optimisation algorithm"))) OR ("_ estimation algorithms")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe optimisation algorithm\") OR (\"_ optimisation algorithm\"))) or (\"_ estimation algorithms\"))".
• Removing quotes may allow a broader search: (((( qoe optimisation algorithm ) OR ( _ optimisation algorithm ))) or ( _ estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimisation algorithm") OR ("_ optimisation algorithm"))) or ("_ estimation algorithms"))*.
