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