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 adam estimation algorithms" » "modified adam estimation algorithm", "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified df estimation algorithms", "modified near estimation 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 adam estimation algorithms") OR ("modified learning convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified adam estimation algorithms ) or ( modified learning convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithms") or ("modified learning convolution algorithms"))*.
