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