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