Perhaps you should try some spelling variations:
"modified invasive estimation algorithmssss" » "modified invasive estimation algorithm", "modified invasive estimation algorithmsss", "modified invasive optimization algorithmssss", "modified invasive optimisation algorithmsss", "modified invasive ventilation algorithmssss", "modified passive estimation algorithmssss"
"modified bayesian estimation algorithms" » "modified bayesian estimation algorithm", "modified bayesian optimization algorithms", "modified bayesian optimisation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified bayesian estimation algorithms\") OR (\"modified invasive estimation algorithmssss\"))~".
• Removing quotes may allow a broader search: (( modified bayesian estimation algorithms ) OR ( modified invasive estimation algorithmssss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified bayesian estimation algorithms") OR ("modified invasive estimation algorithmssss"))*.
