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 network estimation algorithms" » "modified network estimation algorithm", "modified network optimization algorithms", "modified network optimisation algorithm", "certified network estimation algorithms", "defined network estimation algorithms", "modified near estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified network approximation algorithm") OR ("modified network estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified network approximation algorithm\") OR (\"modified network estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified network approximation algorithm ) OR ( modified network estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified network approximation algorithm") OR ("modified network estimation algorithms"))*.
