Perhaps you should try some spelling variations:
"modified quadratic optimization algorithm" » "modified static optimization algorithm", "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quadratic estimation algorithm"
"modified static approximation algorithms" » "modified time approximation 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 static approximation algorithms") OR ("modified quadratic optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified static approximation algorithms ) or ( modified quadratic optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified static approximation algorithms") or ("modified quadratic optimization algorithm"))*.
