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 orcad estimation algorithm" » "modified risk estimation algorithm", "modified orca estimation algorithm"

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

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