Perhaps you should try some spelling variations:
"modified passive optimisation algorithmss" » "modified passive optimization algorithms", "modified passive estimation algorithms", "modified passive estimation algorithm", "modified passive optimization algorithmsss", "modified passive estimation algorithmss", "modified passive estimation algorithmsss", "modified adaptive optimisation algorithmss"
"modified bayesian optimisation algorithm" » "modified bayesian optimization algorithms", "modified bayesian estimation algorithm", "modified bayesian estimation algorithms", "modified bayesian optimization algorithm"

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