Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified trained evolution algorithm" » "modified trained solution algorithm", "modified trained evolutionary algorithm", "modified trained convolution algorithms", "modified time evolution algorithm", "modified trained convolutional algorithm", "modified traces evolution algorithm"

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 trained evolution algorithm") OR ("modified multiobjective optimization algorithms"))~.
• Removing quotes may allow a broader search: (( modified trained evolution algorithm ) or ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trained evolution algorithm") or ("modified multiobjective optimization algorithms"))*.
