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