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