Perhaps you should try some spelling variations:
"modified model evolution algorithm" » "modified model solution algorithm", "modified model evolutionary algorithm", "modified model convolution algorithms", "modified model solutions algorithm", "modified global evolution algorithm", "modified male evolution algorithm"
"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.

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