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