Perhaps you should try some spelling variations:
"modified robust optimization algorithms" » "modified robust optimisation algorithm", "modified robust estimation algorithms", "modified robust estimation algorithm"
"modified parameters optimized algorithms" » "modified parameters optimized algorithm", "modified parameters optimizer algorithms"

You may be able to get more results by adjusting your search query.

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