Perhaps you should try some spelling variations:
"modified df optimisation algorithm" » "modified df optimization algorithms", "modified df estimation algorithm", "modified df estimation algorithms", "modified _ optimisation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified adam optimisation algorithm", "modified bi1 optimisation algorithm"
"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: (("mobile learning convolution algorithm") or ("modified df optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("mobile learning convolution algorithm") OR ("modified df optimisation algorithm")).
• Removing quotes may allow a broader search: (( mobile learning convolution algorithm ) or ( modified df optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("mobile learning convolution algorithm") or ("modified df optimisation algorithm"))*.
