Perhaps you should try some spelling variations:
"qoe optimization algorithm" » "qoe optimization algorithms", "qoe optimisation algorithm", "qoe estimation algorithm", "game optimization algorithm", "_ optimization algorithm", "stage optimization algorithm"
"_ optimized algorithms" » "_ optimizer algorithms", "_ optimization algorithms", "_ optimizer algorithmss"
"done optimized algorithm" » "done optimizer algorithms", "dong optimized algorithm", "one optimized algorithm", "don optimized algorithm"

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