Perhaps you should try some spelling variations:
"modified parameters optimization algorithmss" » "modified parameters optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss", "modified parameters optimization algorithmsss", "modified parameters optimisation algorithmss", "modified parameters estimation algorithmss"
"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"

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