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