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

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

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