Perhaps you should try some spelling variations:
"modified static optimisation algorithm" » "modified static optimization algorithms", "modified static estimation algorithm", "modified static estimation algorithms", "modified static optimization algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm"
"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.

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