Perhaps you should try some spelling variations:
"modified objective predation algorithm" » "modified objective allocation algorithm", "modified objective predators algorithm", "modified objective estimation algorithm"
"modified time solution algorithm" » "modified time evolution algorithm", "modified time convolution algorithms", "modified time evolutionary algorithm", "modified bi1 solution algorithm", "modified male solution algorithm", "modified time solutions algorithm", "modified optimal solution algorithm"

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 objective predation algorithm") OR ("modified time solution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective predation algorithm ) or ( modified time solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective predation algorithm") or ("modified time solution algorithm"))*.
