Perhaps you should try some spelling variations:
"modified bayesian optimisation algorithm" » "modified bayesian optimization algorithms", "modified bayesian estimation algorithm", "modified bayesian estimation algorithms", "modified bayesian optimization algorithm"
"modified parameters optimizer algorithms" » "modified parameters optimized algorithms", "modified parameters optimized algorithm", "modified parameters optimization algorithms"

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