Perhaps you should try some spelling variations:
"modified game optimization algorithms" » "modified game optimisation algorithm", "modified game estimation algorithms", "modified game estimation algorithm", "modified stage optimization algorithms", "modified qoe optimization algorithms", "modified market optimization algorithms", "modified male optimization algorithms", "modified adam optimization algorithms"
"modified parameter estimation algorithmss" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter estimates algorithmss", "modified parameter optimization algorithmss"

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

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