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

You may be able to get more results by adjusting your search query.

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