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

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 notion optimisation algorithm\") OR (\"modified qoe optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified notion optimisation algorithm ) OR ( modified qoe optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimisation algorithm") OR ("modified qoe optimization algorithms"))*.
