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