Perhaps you should try some spelling variations:
"modified adam optimisation algorithm" » "modified adam optimization algorithms", "modified adam estimation algorithm", "modified _ optimisation algorithm", "modified game optimization algorithm", "modified df optimisation algorithm", "modified near optimisation algorithm"
"modified parameter estimation algorithms" » "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter approximation algorithms", "modified parameter estimates 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 parameter estimation algorithms") OR ("modified adam optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified parameter estimation algorithms ) or ( modified adam optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified parameter estimation algorithms") or ("modified adam optimisation algorithm"))*.
