Perhaps you should try some spelling variations:
"modified invasive optimisation algorithms" » "modified invasive optimisation algorithm", "modified invasive estimation algorithms", "modified invasive estimation algorithm", "modified passive optimisation algorithms"
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm"

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

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