Perhaps you should try some spelling variations:
"modified allocation estimation algorithm" » "modified allocation optimization algorithm", "modified motion estimation algorithm"
"modified qoe approximation algorithms" » "modified one approximation algorithms", "modified time approximation algorithms", "modified _ approximation algorithms", "modified male approximation algorithms", "modified bi1 approximation algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified qoe approximation algorithms\") OR (\"modified allocation estimation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified qoe approximation algorithms ) OR ( modified allocation estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified qoe approximation algorithms") OR ("modified allocation estimation algorithm"))*.
