Perhaps you should try some spelling variations:
"modified network approximation algorithm" » "modified network approximation algorithms", "certified network approximation algorithm", "defined network approximation algorithm", "modified near approximation algorithm"
"modified based evaluation algorithm" » "modified based evolution algorithm", "modified based estimation algorithm", "modified based solution algorithm", "modified load evaluation algorithm", "modified based gradation algorithm", "modified large evaluation algorithm", "modified male evaluation algorithm"

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 based evaluation algorithm\") OR (\"modified network approximation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified based evaluation algorithm ) OR ( modified network approximation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified based evaluation algorithm") OR ("modified network approximation algorithm"))*.
