Perhaps you should try some spelling variations:
"modified _ optimization algorithms" » "modified _ optimisation algorithm", "modified _ estimation algorithms", "modified _ estimation algorithm", "modified _ optimisation algorithms", "modified _ 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.

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