Perhaps you should try some spelling variations:
"modified parameters estimation algorithmssss" » "modified parameters estimation algorithm", "modified parameters estimation algorithmsss", "modified parameters optimization algorithmssss", "modified parameters optimisation algorithmsss", "modified parameter estimation algorithmssss", "modified parameter estimates algorithmssss", "modified parameter optimization algorithmssss"
"modified static estimation algorithms" » "modified static estimation algorithm", "modified static optimization algorithms", "modified static optimisation algorithm"

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

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