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 parameter estimation algorithmss" » "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimates algorithmss", "modified parameter optimization algorithmss"

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

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