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