Perhaps you should try some spelling variations:
"modified notion optimization algorithmsssssss" » "modified notion optimization algorithms", "modified network optimization algorithmsssssss", "modified policy optimization algorithmsssssss", "modified allocation optimization algorithmsssssss"
"modified bayesian estimation algorithm" » "modified bayesian optimization algorithm"

You may be able to get more results by adjusting your search query.

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