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