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