Perhaps you should try some spelling variations:
"modified parameters estimation algorithmsss" » "modified parameters estimation algorithms", "modified parameter estimation algorithmsss", "modified parameter estimates algorithmsss", "modified parameter optimization algorithmsss"
"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 bayesian estimation algorithm") OR ("modified parameters estimation algorithmsss"))~.
• Removing quotes may allow a broader search: (( modified bayesian estimation algorithm ) or ( modified parameters estimation algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian estimation algorithm") or ("modified parameters estimation algorithmsss"))*.
