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

Try widening your search to All Fields.

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 algorithmss") or ("modified parameter estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified game optimization algorithmss") OR ("modified parameter estimation algorithms")).
• Removing quotes may allow a broader search: (( modified game optimization algorithmss ) or ( modified parameter estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified game optimization algorithmss") or ("modified parameter estimation algorithms"))*.
