Perhaps you should try some spelling variations:
"modified parameter optimization algorithmss" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithmss"
"modified adam estimation algorithms" » "modified adam estimation algorithm", "modified adam optimization algorithms", "modified adam optimisation algorithm", "modified df estimation algorithms", "modified near estimation algorithms"

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 estimation algorithms") OR ("modified parameter optimization algorithmss"))~.
• Removing quotes may allow a broader search: (( modified adam estimation algorithms ) or ( modified parameter optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithms") or ("modified parameter optimization algorithmss"))*.
