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