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