Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm"
"modified robust estimation algorithmss" » "modified robust estimation algorithms", "modified robust estimation algorithm", "modified robust optimization algorithmss", "modified pose estimation algorithmss", "modified risk estimation algorithmss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified robust estimation algorithmss") or ("modified parameters optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified robust estimation algorithmss") OR ("modified parameters optimization algorithms")).
• Removing quotes may allow a broader search: (( modified robust estimation algorithmss ) or ( modified parameters optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified robust estimation algorithmss") or ("modified parameters optimization algorithms"))*.
