Perhaps you should try some spelling variations:
"modified parameter optimisation algorithmss" » "modified parameter optimisation algorithm", "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameter optimization algorithmss", "modified parameter estimation algorithmss"
"modified static estimation algorithm" » "modified static optimization 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 algorithm") OR ("modified parameter optimisation algorithmss"))~.
• Removing quotes may allow a broader search: (( modified static estimation algorithm ) or ( modified parameter optimisation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified static estimation algorithm") or ("modified parameter optimisation algorithmss"))*.
