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