Perhaps you should try some spelling variations:
"_ optimisation algorithms" » "_ optimisation algorithm", "_ optimization algorithms", "_ estimation algorithms"
"_ optimization algorithm" » "_ optimization algorithms", "_ optimisation algorithm", "_ estimation algorithms"
"qoe estimation algorithm" » "pose estimation algorithm", "_ estimation algorithm", "cover estimations algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("_ optimisation algorithms") or ((("qoe estimation algorithm") or ("_ optimization algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("_ optimisation algorithms") OR ((("qoe estimation algorithm") OR ("_ optimization algorithm")))).
• Removing quotes may allow a broader search: (( _ optimisation algorithms ) or ((( qoe estimation algorithm ) or ( _ optimization algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("_ optimisation algorithms") or ((("qoe estimation algorithm") or ("_ optimization algorithm"))))*.
