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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adam estimation algorithms\") OR (\"modified parameter optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified adam estimation algorithms ) OR ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam estimation algorithms") OR ("modified parameter optimisation algorithm"))*.
