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