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 objective evolution algorithms" » "modified objective evolution algorithm", "modified objective solution algorithm", "modified objective evolutionary algorithm", "modified objective evolutionary algorithms", "modified objective allocation 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 objective evolution algorithms") OR ("modified learning convolution algorithms"))~.
• Removing quotes may allow a broader search: (( modified objective evolution algorithms ) or ( modified learning convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective evolution algorithms") or ("modified learning convolution algorithms"))*.
