Perhaps you should try some spelling variations:
"modified robust optimisation algorithms" » "modified robust optimisation algorithm", "modified robust optimization algorithms", "modified robust estimation algorithms"
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective 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 objective predation algorithm\") OR (\"modified robust optimisation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified objective predation algorithm ) OR ( modified robust optimisation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective predation algorithm") OR ("modified robust optimisation algorithms"))*.
