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