Perhaps you should try some spelling variations:
"modified adaptive ventilation algorithmss" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive quantization algorithmss", "modified invasive ventilation algorithmss", "modified passive ventilation algorithmss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation 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 objective optimization algorithm") OR ("modified adaptive ventilation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"modified adaptive ventilation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified adaptive ventilation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("modified adaptive ventilation algorithmss"))*.
