Perhaps you should try some spelling variations:
"modified based predation algorithm" » "modified based predators algorithm", "modified based estimation algorithm", "modified based prediction algorithm", "modified based gradation algorithm", "modified male predation algorithm"
"modified objective evolution algorithm" » "modified objective evolutionary algorithm", "modified objective allocation algorithm", "modified objective solution algorithm", "modified objective convolution algorithms"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified based predation algorithm") OR ("modified objective evolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified based predation algorithm ) or ( modified objective evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified based predation algorithm") or ("modified objective evolution algorithm"))*.
