Perhaps you should try some spelling variations:
"modified male optimization algorithms" » "modified male optimisation algorithm", "modified male estimation algorithms", "modified male estimation algorithm", "modified game optimization algorithms", "modified market optimization algorithms", "modified stage optimization algorithms"
"modified invasive ventilation algorithms" » "modified invasive estimation algorithms", "modified invasive estimation algorithm", "modified invasive convolution algorithms", "modified adaptive ventilation algorithms", "modified passive ventilation algorithms"

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 algorithms") or ("modified male optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive ventilation algorithms") OR ("modified male optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified invasive ventilation algorithms ) or ( modified male optimization algorithms ))*.
