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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified quadratic optimization algorithms\") OR (\"modified parameters optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( modified quadratic optimization algorithms ) OR ( modified parameters optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified quadratic optimization algorithms") OR ("modified parameters optimized algorithms"))*.
