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