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 caging optimized algorithms" » "modified caging optimized algorithm", "modified caging optimizer algorithms", "modified caging optimization algorithms", "modified aging optimized algorithms", "modified changing optimized algorithms", "modified charging optimized 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 caging optimized algorithms") OR ("modified objective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified caging optimized algorithms ) or ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimized algorithms") or ("modified objective optimisation algorithm"))*.
