Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"modified make convolution algorithms" » "modified make evolution algorithm", "modified make solution algorithm", "modified male convolution algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified make convolution algorithms") or ("modified multiobjective estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified make convolution algorithms") OR ("modified multiobjective estimation algorithms"))*.
• Removing quotes may allow a broader search: (( modified make convolution algorithms ) or ( modified multiobjective estimation algorithms ))*.
