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 model predation algorithm" » "modified model predators algorithm", "modified model estimation algorithm", "modified model reduction algorithm", "modified model predictive algorithm", "modified model predicting algorithm", "modified male predation 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 model predation algorithm") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified model predation algorithm") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified model predation algorithm ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified model predation algorithm") or ("modified objective optimisation algorithm"))*.
