Perhaps you should try some spelling variations:
"modified coverage approximation algorithms" » "modified average approximation algorithms"
"modified trace convolution algorithms" » "modified trace evolution algorithm", "modified trace solution algorithm", "modified trained convolutional algorithms", "modified traces convolution algorithms", "modified male convolution algorithms", "modified orca convolution algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified coverage approximation algorithms") OR ("modified trace convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified coverage approximation algorithms ) or ( modified trace convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified coverage approximation algorithms") or ("modified trace convolution algorithms"))*.
