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

Try widening your search to All Fields.

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