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

Try widening your search to All Fields.

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