Perhaps you should try some spelling variations:
"modified parameter estimation algorithmss" » "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameter optimization algorithmss", "modified parameter optimisation algorithms", "modified parameter estimates algorithmss"
"modified network estimation algorithms" » "modified network estimation algorithm", "modified network optimization algorithms", "modified network optimisation algorithm", "certified network estimation algorithms", "defined network estimation algorithms", "modified near estimation 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 parameter estimation algorithmss") OR ("modified network estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameter estimation algorithmss\") OR (\"modified network estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified parameter estimation algorithmss ) OR ( modified network estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameter estimation algorithmss") OR ("modified network estimation algorithms"))*.
