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