Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimisation algorithms", "modified parameters estimation algorithmss"
"modified topology optimization algorithm" » "modified topology optimisation algorithm", "modified topology estimation algorithm", "modified topology 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 parameters optimization algorithms") OR ("modified topology optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) or ( modified topology optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithms") or ("modified topology optimization algorithm"))*.
