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

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

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