Perhaps you should try some spelling variations:
"modified objective convolution algorithmssssssss" » "modified objective convolution algorithms", "modified objective convolution algorithmsssssssss", "modified objective evolution algorithmssssssss", "modified objective solution algorithmssssssss"
"mobile learning convolution algorithm" » "mobile learning convolution algorithms", "mobile learning evolution algorithm", "mobile learning solution algorithm", "machine learning convolution algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified objective convolution algorithmssssssss") or ("mobile learning convolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective convolution algorithmssssssss") OR ("mobile learning convolution algorithm")).
• Removing quotes may allow a broader search: (( modified objective convolution algorithmssssssss ) or ( mobile learning convolution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective convolution algorithmssssssss") or ("mobile learning convolution algorithm"))*.
