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

Try widening your search to All Fields.

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

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