Perhaps you should try some spelling variations:
"modified caging evolutionary algorithm" » "modified caging evolution algorithm", "modified caging solution algorithm", "modified aging evolutionary algorithm", "modified changing evolutionary algorithm", "modified charging evolutionary algorithm"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation 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 caging evolutionary algorithm") OR ("modified objective allocation algorithm"))~.
• Removing quotes may allow a broader search: (( modified caging evolutionary algorithm ) or ( modified objective allocation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging evolutionary algorithm") or ("modified objective allocation algorithm"))*.
