Perhaps you should try some spelling variations:
"modified rough approximations algorithms" » "modified rough approximation algorithms", "modified rough approximation algorithm", "modified one approximation algorithms"
"modified learning convolution algorithm" » "modified learning convolution algorithms", "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithm", "modified caging convolution algorithm"

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 learning convolution algorithm") OR ("modified rough approximations algorithms"))~.
• Removing quotes may allow a broader search: (( modified learning convolution algorithm ) or ( modified rough approximations algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning convolution algorithm") or ("modified rough approximations algorithms"))*.
