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"
"don optimizer algorithms" » "don optimized algorithms", "don optimization algorithms"
"don optimized algorithm" » "don optimized algorithms", "_ optimized algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("don optimizer algorithms") OR ("don optimized algorithm"))) OR ("qoe optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"don optimizer algorithms\") OR (\"don optimized algorithm\"))) OR (\"qoe optimization algorithm\"))".
• Removing quotes may allow a broader search: (((( don optimizer algorithms ) OR ( don optimized algorithm ))) OR ( qoe optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("don optimizer algorithms") OR ("don optimized algorithm"))) OR ("qoe optimization algorithm"))*.
