Perhaps you should try some spelling variations:
"modified caging source algorithm" » "modified caging our algorithm", "modified caging search algorithm", "modified aging source algorithm", "modified changing source algorithm", "modified charging source 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: (("modified caging source algorithm") OR ("modified network approximation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified caging source algorithm\") OR (\"modified network approximation algorithms\"))".
• Removing quotes may allow a broader search: (( modified caging source algorithm ) OR ( modified network approximation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging source algorithm") OR ("modified network approximation algorithms"))*.
