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