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