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