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

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

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