Perhaps you should try some spelling variations:
"modified qoe optimisation algorithm" » "modified qoe optimization algorithms", "modified qoe estimation algorithm", "modified qoe optimization algorithm", "modified _ optimisation algorithm", "modified game optimization algorithm", "modified male optimisation algorithm", "modified bi1 optimisation algorithm"
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion approximation algorithms", "modified motion estimation algorithms"

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

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