Perhaps you should try some spelling variations:
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified invasive ventilation algorithm" » "modified invasive estimation algorithm", "modified invasive estimation algorithms", "modified invasive evolution algorithm", "modified adaptive ventilation algorithm", "modified passive ventilation 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 invasive ventilation algorithm\") OR (\"modified parameters optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified invasive ventilation algorithm ) OR ( modified parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive ventilation algorithm") OR ("modified parameters optimisation algorithm"))*.
