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

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 optimisation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified _ optimization algorithms") OR ("modified parameters optimisation algorithms")).
• Removing quotes may allow a broader search: (( modified _ optimization algorithms ) or ( modified parameters optimisation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified _ optimization algorithms") or ("modified parameters optimisation algorithms"))*.
