Perhaps you should try some spelling variations:
"modified adam optimization algorithm" » "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified adam estimation algorithms", "modified game optimization algorithm", "modified stage optimization algorithm", "modified _ optimization algorithm", "modified df optimization algorithm", "modified near optimization algorithm"
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive estimation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive estimation algorithm") or ("modified adam optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive estimation algorithm") OR ("modified adam optimization algorithm")).
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithm ) or ( modified adam optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithm") or ("modified adam optimization algorithm"))*.
