Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithm", "modified parameters optimized algorithms"
"modified parameter estimation algorithms" » "modified parameter estimation algorithm", "modified parameter optimisation algorithm", "modified parameter approximation algorithms", "modified parameter estimates algorithms", "modified parameter optimization algorithms"

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 estimation algorithms") or ("modified parameters optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameter estimation algorithms") OR ("modified parameters optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified parameter estimation algorithms ) or ( modified parameters optimization algorithms ))*.
