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