Perhaps you should try some spelling variations:
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"
"modified qoe optimized algorithms" » "modified qoe optimized algorithm", "modified qoe optimizer algorithms", "modified qoe optimization algorithms", "modified _ optimized algorithms", "modified male optimized algorithms", "modified bi1 optimized algorithms"

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

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