Perhaps you should try some spelling variations:
"coarse graining methods algorithm" » "coarse learning methods algorithm", "coarse learning method algorithm", "coarse making methods algorithm", "coarse grain methods algorithm", "coarse grained methods algorithm"
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near approximation algorithms"

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

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