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