Perhaps you should try some spelling variations:
"modified response approximation algorithm" » "modified response approximation algorithms", "modified one approximation algorithm", "modified response association algorithm"
"modified location estimation algorithm" » "modified motion estimation algorithm", "modified carbon estimation algorithm"

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 response approximation algorithm") OR ("modified location estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified response approximation algorithm ) or ( modified location estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified response approximation algorithm") or ("modified location estimation algorithm"))*.
