Perhaps you should try some spelling variations:
"modified invasive ventilation algorithm" » "modified invasive estimation algorithm", "modified invasive estimation algorithms", "modified invasive evolution algorithm", "modified adaptive ventilation algorithm", "modified passive ventilation algorithm"
"modified saline solution algorithm" » "modified saline evolution algorithm", "modified saline convolution algorithms", "modified saline evolutionary algorithm", "modified caging solution algorithm", "modified male solution algorithm", "modified passive solution algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified saline solution algorithm") OR ("modified invasive ventilation algorithm"))~.
• Removing quotes may allow a broader search: (( modified saline solution algorithm ) or ( modified invasive ventilation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified saline solution algorithm") or ("modified invasive ventilation algorithm"))*.
