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

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

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