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 optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation 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 norway convolution algorithms") OR ("modified objective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified norway convolution algorithms ) or ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified norway convolution algorithms") or ("modified objective optimisation algorithm"))*.
