Perhaps you should try some spelling variations:
"modified learning convolution algorithms" » "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithms", "modified caging convolution algorithms"
"modified notion optimizer algorithms" » "modified notion optimized algorithms", "modified notion optimized algorithm", "modified notion optimization 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 algorithms") OR ("modified notion optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( modified learning convolution algorithms ) or ( modified notion optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning convolution algorithms") or ("modified notion optimizer algorithms"))*.
