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