Perhaps you should try some spelling variations:
"modified objective optimisation algorithms" » "modified objective optimisation algorithm", "modified objective optimization algorithms", "modified objective estimation algorithms", "modified multiobjective optimization algorithms"
"modified invasive ventilation algorithm" » "modified invasive estimation algorithm", "modified invasive estimation algorithms", "modified invasive evolution algorithm", "modified adaptive 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 invasive ventilation algorithm") or ("modified objective optimisation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive ventilation algorithm") OR ("modified objective optimisation algorithms")).
• Removing quotes may allow a broader search: (( modified invasive ventilation algorithm ) or ( modified objective optimisation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive ventilation algorithm") or ("modified objective optimisation algorithms"))*.
