Perhaps you should try some spelling variations:
"modified adam optimisation algorithmssss" » "modified adam optimisation algorithm", "modified adam optimization algorithms", "modified _ optimisation algorithmssss", "modified game optimization algorithmssss", "modified df optimisation algorithmssss", "modified near optimisation algorithmssss"
"modified bayesian optimization algorithm" » "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm", "modified bayesian estimation 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 bayesian optimization algorithm") or ("modified adam optimisation algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified bayesian optimization algorithm") OR ("modified adam optimisation algorithmssss")).
• Removing quotes may allow a broader search: (( modified bayesian optimization algorithm ) or ( modified adam optimisation algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian optimization algorithm") or ("modified adam optimisation algorithmssss"))*.
