Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithms", "_ optimization algorithm"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization 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: (((("_ optimized algorithms") or ("_ optimisation algorithm"))) or ("qoe estimation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("_ optimized algorithms") OR ("_ optimisation algorithm"))) OR ("qoe estimation algorithm")).
• Removing quotes may allow a broader search: (((( _ optimized algorithms ) or ( _ optimisation algorithm ))) or ( qoe estimation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("_ optimized algorithms") or ("_ optimisation algorithm"))) or ("qoe estimation algorithm"))*.
