Perhaps you should try some spelling variations:
"modified notion optimization algorithmssss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified network optimization algorithmssss", "modified policy optimization algorithmssss", "modified allocation optimization algorithmssss"
"modified parameter estimation algorithms" » "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimates algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified notion optimization algorithmssss") or ("modified parameter estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion optimization algorithmssss") OR ("modified parameter estimation algorithms"))*.
• Removing quotes may allow a broader search: (( modified notion optimization algorithmssss ) or ( modified parameter estimation algorithms ))*.
