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