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