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