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