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