Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameters optimization 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.

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