Perhaps you should try some spelling variations:
"qoe optimisation algorithm" » "qoe optimization algorithms", "qoe estimation algorithm", "qoe estimation algorithms", "qoe optimization algorithm", "game optimization algorithm", "_ optimization algorithm"
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ estimation algorithms", "_ optimization algorithm"
"_ optimize algorithms" » "_ optimized algorithms", "_ optimizer algorithms", "_ optimized algorithm", "_ optimise 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 ("_ optimize algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("qoe optimisation algorithm") OR ("_ optimisation algorithm"))) OR ("_ optimize algorithms")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"qoe optimisation algorithm\") OR (\"_ optimisation algorithm\"))) or (\"_ optimize algorithms\"))".
• Removing quotes may allow a broader search: (((( qoe optimisation algorithm ) OR ( _ optimisation algorithm ))) or ( _ optimize algorithms )).
• Adding a wildcard symbol may retrieve word variants: (((("qoe optimisation algorithm") OR ("_ optimisation algorithm"))) or ("_ optimize algorithms"))*.
