Perhaps you should try some spelling variations:
"modified notion approximation algorithms" » "modified network approximation algorithms", "modified time approximation algorithms", "modified one approximation algorithms"
"modified near evolution algorithm" » "modified near solution algorithm", "modified near evolutionary algorithm", "modified near convolution algorithms", "modified early evolution algorithm", "modified legal revolution algorithm", "modified seird evolution algorithm", "modified adam evolution algorithm"

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

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