Perhaps you should try some spelling variations:
"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"
"modified network approximation algorithms" » "certified network approximation algorithms", "defined network approximation algorithms", "modified near approximation 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 trace convolution algorithms") OR ("modified network approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified trace convolution algorithms ) or ( modified network approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trace convolution algorithms") or ("modified network approximation algorithms"))*.
