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 adaptive ventilation algorithm" » "modified adaptive estimation algorithm", "modified adaptive estimation algorithms", "modified adaptive evolution algorithm", "modified adaptive quantization algorithm", "modified invasive ventilation algorithm", "modified passive ventilation 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 adaptive ventilation algorithm") OR ("modified parameters optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified adaptive ventilation algorithm ) or ( modified parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive ventilation algorithm") or ("modified parameters optimisation algorithm"))*.
