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