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

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 optimization algorithm") OR ("modified topology optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified parameters optimization algorithm\") OR (\"modified topology optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified parameters optimization algorithm ) OR ( modified topology optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified parameters optimization algorithm") OR ("modified topology optimization algorithms"))*.
