Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"code learning convolution algorithms" » "code learning evolution algorithm", "code learning solution algorithm", "how learning convolution algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"code learning convolution algorithms\") OR (\"modified multiobjective optimized algorithm\"))~".
• Removing quotes may allow a broader search: (( code learning convolution algorithms ) OR ( modified multiobjective optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("code learning convolution algorithms") OR ("modified multiobjective optimized algorithm"))*.
