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