Perhaps you should try some spelling variations:
"modified near approximation algorithm" » "modified near approximation algorithms", "modified one approximation algorithm", "modified network approximation algorithm", "modified _ approximation algorithm", "modified seird approximation algorithm", "modified adam approximation algorithm"
"modified objective solution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms"

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