Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"
"modified fire predation algorithm" » "modified fire predators algorithm", "modified fire estimation algorithm", "modified fire prediction algorithm", "modified seird predation algorithm", "modified bi1 predation algorithm", "modified male predation 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 fire predation algorithm\") OR (\"modified objective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified fire predation algorithm ) OR ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified fire predation algorithm") OR ("modified objective optimisation algorithm"))*.
