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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified response optimization algorithm") OR ("modified invasive estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified response optimization algorithm\") OR (\"modified invasive estimation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified response optimization algorithm ) OR ( modified invasive estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified response optimization algorithm") OR ("modified invasive estimation algorithmss"))*.
