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

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