Perhaps you should try some spelling variations:
"modified one approximation algorithm" » "modified one approximation algorithms", "modified time approximation algorithm", "modified _ approximation algorithm", "modified rough approximations algorithm", "modified male approximation algorithm", "modified near approximation algorithm", "modified orca approximation algorithm"
"modified based solution algorithm" » "modified based evolution algorithm", "modified based convolution algorithms", "modified based evolutionary algorithm", "modified male solution algorithm", "modified based solutions algorithm", "modified water solution algorithm", "modified based evaluation 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 based solution algorithm") or ("modified one approximation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified based solution algorithm") OR ("modified one approximation algorithm")).
• Removing quotes may allow a broader search: (( modified based solution algorithm ) or ( modified one approximation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified based solution algorithm") or ("modified one approximation algorithm"))*.
