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