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