Perhaps you should try some spelling variations:
"defined network optimization algorithm" » "defined network optimization algorithms", "defined network optimisation algorithm", "defined network estimation algorithm", "designed network optimization algorithm"
"modified invasive estimation algorithms" » "modified invasive estimation algorithm", "modified invasive optimization algorithms", "modified invasive optimisation algorithm", "modified invasive ventilation algorithms", "modified passive estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("defined network optimization algorithm") OR ("modified invasive estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"defined network optimization algorithm\") OR (\"modified invasive estimation algorithms\"))".
• Removing quotes may allow a broader search: (( defined network optimization algorithm ) OR ( modified invasive estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("defined network optimization algorithm") OR ("modified invasive estimation algorithms"))*.
