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