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