Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"modified df convolution algorithms" » "modified df evolution algorithm", "modified df solution algorithm", "modified d convolutional algorithms", "modified _ convolution algorithms", "modified adam convolution algorithms", "modified bi1 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 multiobjective optimizer algorithms\") OR (\"modified df convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective optimizer algorithms ) OR ( modified df convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimizer algorithms") OR ("modified df convolution algorithms"))*.
