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