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