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