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