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