Perhaps you should try some spelling variations:
"modified learning convolution algorithm" » "modified learning convolution algorithms", "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithm", "modified caging convolution algorithm"
"modified one approximation algorithms" » "modified time approximation algorithms", "modified _ approximation algorithms", "modified rough approximations algorithms", "modified male approximation algorithms", "modified near approximation algorithms", "modified orca 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 learning convolution algorithm") OR ("modified one approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified learning convolution algorithm ) or ( modified one approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning convolution algorithm") or ("modified one approximation algorithms"))*.
