Perhaps you should try some spelling variations:
"modified topology optimisation algorithmss" » "modified topology optimisation algorithm", "modified topology optimization algorithms", "modified topology estimation algorithm", "modified topology optimization algorithmss", "modified policy optimization algorithmss"
"modified parameters estimation algorithms" » "modified parameter estimation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms", "modified parameters estimation algorithm", "modified parameters optimization algorithms", "modified parameters optimisation 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 topology optimisation algorithmss") OR ("modified parameters estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified topology optimisation algorithmss\") OR (\"modified parameters estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified topology optimisation algorithmss ) OR ( modified parameters estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified topology optimisation algorithmss") OR ("modified parameters estimation algorithms"))*.
