Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"modified nacl convolution algorithmss" » "modified nacl convolution algorithms", "modified nacl evolution algorithm", "modified nacl solution algorithmss", "modified male convolution algorithmss", "modified near convolution algorithmss", "modified orca convolution algorithmss"

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 nacl convolution algorithmss") OR ("modified multiobjective estimation algorithm"))~.
• Removing quotes may allow a broader search: (( modified nacl convolution algorithmss ) or ( modified multiobjective estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified nacl convolution algorithmss") or ("modified multiobjective estimation algorithm"))*.
