Perhaps you should try some spelling variations:
"modified topology optimisation algorithms" » "modified topology optimisation algorithm", "modified topology optimization algorithms", "modified topology estimation algorithms", "modified policy optimization algorithms"
"modified parameters estimation algorithm" » "modified parameter estimation algorithm", "modified parameter estimates algorithm", "modified parameter optimization 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 estimation algorithm") or ("modified topology optimisation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters estimation algorithm") OR ("modified topology optimisation algorithms")).
• Removing quotes may allow a broader search: (( modified parameters estimation algorithm ) or ( modified topology optimisation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters estimation algorithm") or ("modified topology optimisation algorithms"))*.
