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 one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca approximation 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 parameters optimization algorithms") or ("modified one approximation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified parameters optimization algorithms") OR ("modified one approximation algorithms"))*.
• Removing quotes may allow a broader search: (( modified parameters optimization algorithms ) or ( modified one approximation algorithms ))*.
