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