Perhaps you should try some spelling variations:
"modified coverage approximation algorithms" » "modified average approximation algorithms"
"modified based evaluation algorithms" » "modified based evolution algorithm", "modified based estimation algorithms", "modified based convolution algorithms", "modified load evaluation algorithms", "modified based gradation algorithms", "modified large evaluation algorithms", "modified male evaluation 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 coverage approximation algorithms") OR ("modified based evaluation algorithms"))~.
• Removing quotes may allow a broader search: (( modified coverage approximation algorithms ) or ( modified based evaluation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified coverage approximation algorithms") or ("modified based evaluation algorithms"))*.
